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 by applying compressive pressure to a test specimen (usually of either a cuboid or cylindrical geometry) using platens or specialized .mature wood. The trunk cross-section in both the sapwood and heart-wood is characterized by distinctive annual growth rings. These occur because the wood formed during the early part of the season when the growth is more active (early-wood) is less dense and therefore lighter in colour than that produced later in the season (latewood). Under condi-Abstract. Experimental and numerical analysis of a compression test carried out on samples of as-received and thermally-treated beech (Fagus sylvatica L.) wood is presented.In a normal climate, samples with the dimensions of 20 x 20 x 20 mm were exposed to static compressive loads parallel and transverse to the grain.
