The maximum ordinate in the stress-strain diagram

Also called tensile strength

The strength of the material at rupture

Also known as the breaking strength

The point on a plane surface that corresponds to the center of gravity

Center of mass

A measure of the bending stiffness of a structural member's cross sectional

Material property that enables deformity upon the force applied and recovers after removing such force

Material property that enables the material to deform under tensile load

Material property that has the ability to deform under compressive strength

Material property that has the ability to absorb energy before rupturing

The ratio between the unit stress and unit deformation caused by stress

Also known as Young's Modulus

Derived by Hooke's Law

Also called Modulus of Rigidity

Also called Modulus of Torsion

The change in strain (deformation) of a material with respect to time

A temporary change in the shape the body produced by a stress less than the elastic limit of the material

Inelastic strain in a material

Gradual permanent deformation produced by continuous application of loads

The time-dependent decrease in strength capacity in a constrained material

Failure to maintain elastic limit subjected to repeated series of stress

Study of external forces applied on a body inducing any motion

Representative force of the cummulative effects of forces
