This vCalc equation, the Elastic Longitudinal Deformation equation, computes the deformation factor used in the calculation of strain due to longitudinal loading.¹

Longitudinal deformation in the case of uniaxial deformation can be seen as a change of the cross section of a pipe.

Inputs

P - the loading force applied as an axial torque
L - length of the member to which a toque is applied
A - the cross sectional area
E - the Modulus of Elasticity
