shear test

A shear test measures how well a material can resist forces that attempt to slide or shift its layers relative to each other. In this test, a sample is subjected to a force applied parallel to its surface until it deforms or breaks. It's like pushing on a deck of cards sideways to see how much force it takes to make the cards slide apart. This helps engineers understand the material's strength and stability under forces such as sliding, shearing, or twisting, which is essential for ensuring safety and durability in structures and products.
