Shear Stress vs. Tensile Stress: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on November 29, 2023
Shear stress is the force per unit area causing layers to slide past each other, while tensile stress is the stretching force per unit area.

Key Differences

Shear stress occurs when forces are applied parallel to a material's surface, causing layers to slide over each other. In contrast, tensile stress stretches material by pulling it apart along its length.

Shear stress is often observed in materials subjected to twisting or shearing forces. Tensile stress, however, is seen in materials under tension, like ropes or cables.
