Here a sample is subjected to a controlled tension until it fails. Properties that are directly measured via a tensile test are yield/ultimate tensile strength, maximum elongation (ductility), modulus and reduction in area.
Is a measure of the toughness of a material and involves measuring the energy required to fracture a ‘V’ notched specimen at a particular temperature, which can be as low as -50oC.
This is an indirect, somewhat qualitative, measure of the strength of a material. It is obtained by depressing a known shape (usually a ball) at a given load into the material and evaluating the resulting deformation.
This is one of the most important properties of any material for many design applications and describes the ability of a material containing a crack to resist fracture.
Is the weakening of a material caused by repeatedly applied loads. It is the progressive and localised structural damage that occurs when a material is subjected to a cyclic load.
A sudden and complete failure of a component when held at a constant temperature and at a definite constant load in a given environment for a given period of time.
