What is a stress relaxation test?

Stress-Relaxation Testing. This test method is used to determine a sample's creep properties when subjected to a prolonged tensile or compressive load at a constant temperature. The rate of deformation of a sample to stress at a constant temperature is known as the creep rate.

Also to know is, what is stress relaxation of blood vessels?

Regulation of arterial blood pressure - Vascular stress relaxation response. This mechanism occurs as a result of the degree of pressure on the vascular smooth muscle cells. An increase in arterial blood pressure causes the smooth muscle cells to relax, causing the vessel wall to stretch.

What is creep relaxation?

two terms are sometimes used interchangeably, although they are really different. Creep is an increase in plastic strain under constant stress. Stress relaxation is a decrease in stress under constant strain.
