Compression testing is one of the most fundamental types of mechanical testing, alongside tensile and flexion tests. Compression tests are used to determine a material’s behavior under applied crushing loads, and are typically conducted .In a piece of wood, there are fibers (refer figure 1 [4]), going in one direction and this direction is referred to as ”with the grain”. Compression test of wood gives different result along the grain and perpendicular to grain. I. INTRODUCTION .A compression test is one of the most fundamental mechanical tests that can be performed on a material, product, or component. Our compression test machines measure characteristics such as yield strength, ultimate strength, modulus of elasticity, and stress-strain. Each compression test machine is configured to your testing needs by our application engineers with the correct .The Unconfined Compression Test is a laboratory test used to derive the Unconfirmed Compressive Strength (UCS) of a rock specimen. Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a .

Lab 6 - Compression Testing of Wood - Free download as PDF File (.pdf), Text File (.txt) or read online for free. This lab report summarizes compression testing of oak and pine wood samples with loading both parallel and perpendicular to the grain. Four wood samples - two oak and two pine - were tested under each loading condition. The results showed that wood . In the compression test, a standardized specimen is loaded under compressive stress until it breaks or until a first crack appears. The testing of materials under compressive stress is carried out in the so-called compression test.Standardized round specimens are used, which are much thicker than tensile specimens.The maximum height of the sample is twice the .The testing procedure to quantify the critical soil properties associated with soil consolidation is the Oedometer Test. The term “Oedometer” derives from the Ancient Greek language and means “to swell”. The test is one of the most commonly conducted, and important, laboratory tests in geotechnical engineering.
Detailed information about mechanical properties of wood and wood products also can be found in the following literature: Wood Handbook (1999). Wood as an engineering material. USDA Forest Products Lab: Madison, Wisconsin. Hoadley, B. (2000). Understanding Wood. The Taunton Press: Newtown, Connecticut.
