Tensile test. strain rate – rapid stress application, as in an impact test, measures the ability of the material to absorb energy as it fails. temperature effect – at high temperatures, materials deform continuously under an applied stress, as measured by the creep test. repeated application of stresses below the failure stress determined. Figure 8.4 effect of stress and temperature on strain time creep curves in this relation, if t >t transient then ε = ε i bσ mt dσ α (8.5) and the strain rate is the steady state or minimum strain rate: dε dt = bσ m = ε ˙ ss (8.6) the steady state or minimum strain rate is often used as a design tool. for. Flow stress. in materials science the flow stress, typically denoted as yf (or ), is defined as the instantaneous value of stress required to continue plastically deforming a material to keep it flowing. it is most commonly, though not exclusively, used in reference to metals. on a stress strain curve, the flow stress can be found anywhere.

Stress strain curves david roylance department of materials science and engineering massachusetts institute of technology cambridge, ma 02139 august 23, 2001. Ductile materials usually fail on planes that correspond to the maximum shear stresses (45°). a cup and cone failure is typical for ductile materials with the sides of cup and cone inclined at approximately 45° to the specimen axis. poisson’s ratio – the ratio of lateral or transverse strain to the longitudinal strain. ν= ε −.
