When a force acts on an object, it can create stress and strain within it. Stress is an internal force per unit area, and the deformation the object undergoes due to the stress is the strain. Two of the most common types of stress and strain are tensile and compressive stress and strain...
If the tensile stress is applied parallel to the object rather than perpendicular to it, the stress is known as the shear force or shear stress. And the compressive force is opposite to the tensile stress and we can see this force being used in the construction field, to build concrete pil...
Tensile strength (TS) at break measures the maximum stress a plastic specimen can withstand while being stretched before breaking. Some materials can break sharply (brittle failure). While others will deform or elongate before breaking. It is measured as the tensile or compressive load required to...
Typically, ceramics perform poorly in tension, while metals are quite good. Fibres such as glass, Kevlar and carbon fibre are often added polymeric materials in the direction of the tensile force to reinforce or improve their tensile strength. Compressive Strength Compressive strength is defined as ...

Another study looked at the effect of minor alloying elements on microcrack formation in LPBF Hastelloy X and the influence of hot cracking on tensile and compressive properties [334]. They found that a reduction in minor alloying elements resulted in the elimination of hot cracking in AB LPBF ...
(C) Slip band structure produced by alternating tensile and compressive stresses. Unlike case B, microcrack-like surface intrusions form. When the applied loading is cyclic or alternately tensile and compressive as indicated in Fig. 7-9C, slip bands can extend outward as well as inward, leaving...

In order to be effective, these stresses must be tensile (as opposed to compressive). One method of controlling stress corrosion is to eliminate stress, or at least reduce it below the threshold stress for stress corrosion cracking. Residual stresses can be relieved by stress-relief annealing, ...
The effect of mechanical stresses on the dynamic Young's modulus measured by the ultrasonic wave method was examined for an isotropic graphite. Young's modulus of the graphite decreased with increasing applied stress, though the amount of its decrease was different between tensile and compressive ...
