When put under compression (or any other type of stress), every material will suffer some deformation, even if imperceptible, that causes the average relative positions of its atoms and …

A diagram of the compression set A experiment (under constant force in air). This has the formal name compression set under constant force in air. In compression set A a force of 1.8 kN is …

Compressive strength Measuring the compressive strength of a steel drum In mechanics, compressive strength (or compression strength) is the capacity of a material or structure to …

F is the force applied on the object, and A is its cross-sectional area. As shown in the formula above, compressive stress is typically represented by negative values to indicate that there is …

Hooke's law is a first-order linear approximation to the real response of springs and other elastic bodies to applied forces. It fails once the forces exceed some limit, since no material can be …

Shear force Shearing forces act in one direction at the top, and the opposite direction at the bottom, causing shearing deformation. A crack or tear may develop in a body from parallel …

Free body diagram Block on a ramp and corresponding free body diagram of the block. In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical …

A compression member is a structural element that primarily resists forces, which act to shorten or compress the member along its length. Commonly found in engineering and architectural …
