Breaking strength

from Wikipedia, the free encyclopedia

Breaking strength , including static strength , is the mechanical stress in strength theory that leads to breakage in a component with a uniform increase in the load . Depending on the type of stress , the breaking strength is differentiated into

These strengths are determined by tests (e.g. tensile test ) on standardized test specimens as material parameters. Their numerical values ​​differ from one another, even for the same material .

The breaking strength has the unit of tension and is therefore given as the quotient of the breaking load ( force ) divided by the cross-sectional area of the test specimen in Pascals (mostly megapascals, MPa); one megapascal corresponds to a force of one newton per square millimeter of area.

Another type of strength under static load is the yield point , under dynamic load the fatigue strength or inert strength are decisive.
