STREMA_1

the constant of proportionality between stress and strain.

defined as force per unit area.

ratio of lateral strain to longitudinal strain.

is a plot of the stress on the ordinate (y-axis) versus the strain on the abscissa (x-axis)

the greatest stress that one can still see a linear relation between stress and strain.

the change in length per unit length.

This is a material property and a measure of the energy a material can contain. It is the area under the stress-strain diagram up to the proportional limit.

It is the study of the internal effect of external forces applied to structural member.

The applied force is perpendicular to the resisting area

The applied force is parallel to the resisting area
