Definitions Flashcards
What is density?
The measure of mass per unit volume
What is the unit of density?
Kg/m3
What is Fatigue?
When a material is subjected to cyclic loadings (it start to crack after sufficient repetitions)
What is elasticity?
The ability to return to its original shape from a deformed state after external forces have been removed.
What is unit stress?
Force per unit area
What is Tension?
To stretch or lengthen a material
What is compression?
To a squeeze / press or compress material
What is shearing?
To pull in opposite directions
What is Combined stress?
A combination of tensile and shear stress
What is elastic limit?
The maximum stress to which a material may be subjected and still return to its original shape upon release of the load.
What is Yield strength?
The maximum stress that can be applied to a material without permanent deformation of the material.
