mechanical stress
physical quantity that expresses internal forces in a continuous material
shear stress
component of stress coplanar with a material cross section
thermal stress
mechanical stress caused by change in material's temperature
stress tensor
tensor that describes the state of stress at a point inside a material
residual stress
remaining stress in a solid material after removal of the original cause
virial stress
measure of mechanical stress on an atomic scale for homogeneous systems
creep limit
the tension, which results in a predetermined temperature and load duration at a specific plastic elongation
normal stress
force component perpendicular to a surface element divided by the area of that surface element
bending stress
stress caused by bending
compressive strength
capacity of a material or structure to withstand loads tending to reduce size, which withstands loads tending to elongate
elastic limit
Mechanical limit
ultimate tensile strength
capacity of a material or structure to withstand loads tending to elongate; resists tension (being pulled apart); measured by the maximum stress that a material can withstand while being stretched or pulled before breaking
compressive stress
Structural failure in long, slender structural elements such as columns or truss bars
plane stress
condition where the stress vector is zero across a particular plane
