Fracture Point
The point where a material breaks after reaching its stress and strain limits, beyond elastic and plastic deformation.
Strain
The change in length of a material divided by its original length, caused by stress.
Stress
A force applied to a material divided by its cross-sectional area. Measured in Pascals (Pa).
Stress-strain graph
A visual representation of how a material responds to a load.
Ultimate Strength
The maximum stress a material can withstand before breaking.
Yield Strength
The maximum stress a material can handle before plastic deformation begins.
Young's Modulus
A measure of a material’s stiffness, defined as stress divided by strain.
