compressive stress

[kəm′pres·iv ′stres]
(mechanics)
A stress which causes an elastic body to shorten in the direction of the applied force.

compressive stress

1.The stress which resists the shortening effect of an external compressive force.
2. For a test specimen: the compressive load per unit area of original cross section carried by the test specimen at any time during a compression test.

Predictions assuming viscous-elastic (constant elastic shear modulus) and then visco-elastic behavior, showed an increase in the subsurface compressive stress with the PS, but a reduction with the ABS.
6% drop in compressive stress between 500 and 4,000 hours).
exhibits a higher creep deformation than that with the same shear stress but a superimposed axial compressive stress, case 2, and this difference can be attributed to the hydrostatic stress effect.
In every cycle, the resistance decreased as the compressive stress increased, such that the maximum stress corresponded to the minimum resistance and the minimum stress corresponded to the maximum resistance.
In Part II of this series of papers, the R [geq] 0 regime will be addressed and the discussion will center on the nature of the fatigue damage in the absence of an externally imposed compressive stress.
Given the relatively narrow range of compressive stress experienced by crazes during these experiments at R = 0, it is feasible that the relationship between recovery and crack growth rate could be approximately linear.
When the rocket fires, hot gases from burning propellant place the seal under considerable compressive stress.
Partial relaxation of this stress then occurred and this caused the formation of compressive stress when the sample was restored to a higher temperature, an effect that then repeated on repeating the conditioning cycle.
It can induce interior residual compressive stress due to the shift of the distraction peak toward the left after the finishing.
To assess the thermal stresses in the film during heating for the temperature range covered in the experiments, its biaxial compressive stress ([[alpha].
When bent, the compressive stress will cause a buckle on the inside radius.
These manual procedures could trigger the t [right arrow] m phase transformation and grinding, creating a compressive stress layer, due to an increase in the volume of the material (zirconia) by approximately 3%, in addition to producing some surface defects in the material.
