Mechanical stress and strain definition
WebStress is the measure of an external force acting over the cross sectional area of an object. Stress has units of force per area: N/m 2 (SI) or lb/in 2 (US). The SI units are commonly referred to as Pascals, abbreviated Pa. WebFeb 16, 2006 · Strain is the response of a material to stress. It is defined as the change in length of the material under stress ( L' − L0) divided by the original length ( L0 ). For a material under tension, the material may show an incremental increase in length. For a material under compression, the material may show an incremental decrease in length.
