Web1 Jan 1986 · This alloy exhibits a large plastic engineering strain of 83% and plastic true strain of 177% with a flow stress at 4.3% deformation of 425 MPa. During compression, … Web26 Nov 2024 · It is common during uniaxial (tensile or compressive) testing to equate the stress to the force divided by the original sectional area and the strain to the change in length (along the loading direction) divided by the original length. In fact, these are “ engineering ” or “ nominal ” values.
