Material Internal Force Calculator

getcalc.com's Engineering Stress (σ) Calculator is an online mechanical engineering tool for material analysis to measure the ratio between applied load or force & cross-sectional area of a material, in both US customary & metric (SI) units.

Definition & Formula

Engineering Stress, often represented by the Greek symbol σ, is a physical quantity used to express the internal forces or pressure acting on the material or object. It's one of a most important functions of strength of materials, frequently used to analyse the stress of material.
