Plastic behavior plays a big role in how building materials fail. Here’s how it works:
Yielding: This happens when materials can’t take much stress anymore. For example, structural steel fails when the stress goes beyond about 250 MPa.
Ductility: Some materials, like mild steel, can bend a lot before breaking. This is important during earthquakes because it helps absorb energy and prevent sudden failures.
Work Hardening: Some materials actually get stronger when they are deformed. For example, when copper is stretched, it can become up to 40% stronger.
Failure Modes: When materials start to lose their strength, they can fail in different ways. For thin columns, a common issue is buckling. This occurs when the load exceeds a critical point, which can be figured out using a formula.
So, understanding plastic behavior helps us know how materials will act under stress and which might fail first.
