Materials 1st Review

Direct tension failure

axial pulling force overcomes the tensile strength of the material on which the force is exerted

Direct compression failure

direct axial pushing force causes the material to crush

Column buckling

long, straight, and slender member bends and buckles by a significant amount before any of the material actually fails

Direct shear

cutting action is applied as you would see with scissors, tin snips, or punches.

Torsional shear stress

load-carrying member is twisted about its long axis due to an applied torque at one or more points along the member, resisted by a reaction torque at one or more other points.

Bending stress

member carries a load perpendicular to its long axis while being supported in a stable manner, thereby “bending” the member, now called a “beam.”
