Mechanical Properties
Mechanical Properties
A measure of a material's resistance to deformation, fracture, and crack growth when subjected to external forces.
Fracture
Fracture
Breaking of a material due to stresses and strains exceeding its maximum withstanding capacity.
Stress and Strain
Stress and Strain
Often used to quantify mechanical properties, these terms describe the intensity of internal forces and the deformation of a material, respectively.
