WOOD – TEST METHODS
Contact
Wood and wood products are used in various forms and combinations depending on the area of use and intended use. As a building material and renewable raw material, wood offers many ecological and economic advantages. Many wood products subject to mechanical testing are used in construction, furniture and general purpose manufacturing.The most common reason for testing wood and wood products is to determine their tensile, compressive and flexural strength.

MEZERA
The measured strength of wood and wood material determines whether they are suitable for a specific purpose. A variety of static and dynamic test methods are used for wood products to determine their suitability for a particular application. These methods usually involve simple tensile, compressive and bending tests. For example, in tensile tests, the wood material is placed on a testing machine, and tension is applied to its ends. In compression tests, the wooden products are compressed at both ends, while in bending tests, the load is applied to the center of the specimen.

TENSILE TEST OF WOOD
Tensile wood tests represent the basic and key method for assessing the ability of wood to withstand tensile forces. These tests are necessary to understand its mechanical properties and are used in the design and construction of wooden structures in construction, furniture, furniture manufacturing and other industries. Here’s a look at the meaning and process of timber tensile testing.Assessment of material strength: wood tensile tests are designed to determine the strength of a material against tensile forces. During the test, a uniform tensile force is applied to the wood sample, gradually increasing up to the point of failure. This test makes it possible to measure the maximum tensile force that wood can withstand and to determine its yield strength, which is the point at which the material begins to permanently deform.Valuable information for construction: the results of timber tensile tests provide important information for engineers and designers in the design of timber structures. Determining the tensile strength of wood makes it possible to properly dimension supporting elements such as beams, posts, rods and other structural elements. This ensures the safety, stability and long-term durability of wooden structures.Various Factors Affecting Results: The results of wood tensile tests can be affected by various factors such as wood type, humidity, temperature, fiber length and more. Therefore, it is important to perform tests under standardized conditions and take all these factors into account when interpreting the results. Practical applications: Wood tensile tests are an invaluable tool for furniture makers, structural engineers, architects and other professionals working with wood materials. These tests provide important information about the strength and durability of wood, leading to safer and more reliable structures and products.
Tensile tests of wood are an essential tool for assessing its mechanical properties and ability to withstand tensile forces. These tests provide important information for the construction and design of wooden structures and products, which contributes to the safety, stability and long-term durability of the use of wood in various applications.

BENDING TEST OF WOOD
Bending tests of wood are a key tool for assessing its mechanical properties and behavior under various loading conditions. These tests allow engineers and designers to obtain important information about the strength, elasticity and modulus of elasticity of wood, which is essential for the proper design and construction of wooden structures. Here’s a look at wood bending tests and what they mean.3-point and 4-point bending: wood bending tests are usually performed using 3-point or 4-point bending. In 3-point bending, a force is applied to the wood specimen midway between two supports, while in 4-point bending, two forces are applied at opposite ends of the specimen with two supports in the middle. This difference in test geometry can affect the results and allows different information about the behavior of the wood to be obtained.Modulus of elasticity: one of the key parameters that are determined in bending tests of wood is the modulus of elasticity (also called modulus of elasticity). This parameter indicates the wood’s ability to resist deformation when a bending load is applied. Higher values of the modulus of elasticity indicate greater stiffness of the material and the ability to withstand bending loads.Practical significance: in practice, wood bending tests are invaluable to engineers and designers in the design and construction of wood structures such as beams, beams, parquets, wooden floors and more. The obtained information on the modulus of elasticity and bending resistance of wood allows for the correct dimensioning of structural elements and ensures safety, stability and long-term reliability.
Wood bending tests are usually performed according to standardized procedures and regulatory requirements that ensure consistent and accurate results. These standards establish testing conditions, sample geometry, measurement methods and other parameters that are important for the correct performance of tests and interpretation of results.Bending tests of wood are an essential tool for understanding its mechanical properties and behavior under various loading conditions. These tests make it possible to obtain important information about the modulus of elasticity, resistance and stiffness of wood, which is essential for the successful design and construction of wooden structures in the construction, furniture and other industries.

PRESSURE TESTS OF WOOD
The compression test of wood is necessary to assess the resistance of wood to compressive forces, which is especially crucial in the field of construction, where materials are under significant compressive loads, for example in the construction of columns, beams and supports. This test makes it possible to determine the behavior of the material under compressive loads and provides important information for engineering and construction applications. Compression testing of wood is usually carried out according to standardized procedures, using compression fixtures and extensometers including normative requirements that ensure consistent and accurate results. These standards establish testing conditions, sample geometry, measurement methods and other parameters that are important for the correct performance of tests and interpretation of results.

CYCLIC LOADING OF WOOD
The cyclic wood test is a special type of test designed to assess the behavior of wood under repeated loading. This type of test is necessary to understand how wood reacts to repeated loading, which is especially important for the construction of bridges, buildings and other structures that are subjected to cyclic stress.Testing possibilities: servo-hydraulic and electrodynamic testing machines or H.10 series test benches from LABORTECH enable testing of large glued beams according to ČSN EN 12512 and joint tests according to ČSN EN 12512 or ISO 21581. These standards provide precise procedures for carrying out cyclic tests of wood and establish requirements for performance and reliability of the material. These standards specify how tests should be performed, what criteria should be met and what results should be obtained. This makes the test results relevant and applicable for structural design and construction.

IMPACT TEST OF WOOD MATERIALS
LABORTECH, a leading manufacturer of testing machines, is known for its cutting-edge technology for impact testing wooden materials. By wood toughness we mean the wood’s resistance to dynamic (impact) stress, which is determined by a puncture test. In the impact test, a pendulum hammer strikes the center of the test specimen from a constant height. We determine the energy required to break a body under the action of a dynamic load. By the appearance of the quarry, we can determine the quality of the wood. The toughness of wood is strongly influenced by wood defects, wood drying at higher temperatures, forced impregnation, etc.
Díky přesným testovacím strojům od LABORTECH jsou výrobci schopni provádět tyto klíčové testy s vysokou přesností a spolehlivostí, což je nezbytné pro zajištění jakosti – kvality dřeva a dřevěných produktů ve stavebnictví.
