is yield strength?
Stress at which a material starts to deform plastically. - What
is Young’s modulus?
Ratio of stress to strain in the elastic range. - What
is compression test?
Test to determine behavior of material under compressive load. - What
is bending test?
Test to find flexural strength and modulus of rupture. - What
is fatigue of material?
Weakening of material due to repeated loading and unloading cycles. - What
is microstructure?
The internal structure of material observed under a microscope. - Why
is microstructure study important?
It helps to understand grain size, phase distribution, and material properties. - What
