In the realm of material science and engineering, the evaluation of material strength is crucial. One of the key methods for this purpose is compression testing, which measures the ability of a material to withstand compressive forces. In addition, the flexural modulus, often assessed alongside compression testing, provides further insight into a material’s resistance to bending. This article will shed light on compression testing and the significance of flexural modulus in assessing material strength.
Compression testing involves subjecting a material to compressive forces until it deforms or fails. A sample is placed between an upper and lower fixture, such as parallel compression plates or specific application-driven fixtures. The fixtures are installed on a universal testing machine (UTM), and a gradually increasing force is applied until the material deforms to the desired height or force, or fractures.
