yield strength
Yield strength is a material property that indicates the stress level at which a material begins to deform permanently. In simpler terms, it’s the point where a material, like metal or plastic, can no longer return to its original shape after being stretched or compressed. Before reaching this point, the material can bend or twist and revert back to normal, but beyond the yield strength, it will retain some of that deformation. Understanding yield strength is crucial in engineering and construction to ensure that structures can withstand loads without permanently bending or breaking.

Yield strength is a material's ability to withstand stress without permanently deforming. When a force is applied to a material, it can bend or stretch; yield strength is the maximum stress that can be applied before the material changes shape permanently. Beyond this point, the material won't return to its original form. It’s a crucial property in engineering and construction, ensuring that structures like buildings and bridges can support loads safely without failing. In essence, yield strength helps determine how much force a material can take before it starts to break down.
