The hypothesis used in developing the stress and strain in the shaft is that all points on a cross-section of the shaft experience the same angle of twist. The angle of twist for a section of length L ...

There are two main types of stress - normal stress, which acts perpendicular to a surface, and shear stress, which acts parallel to a surface. Strain is a measure of the displacements that occurs ...

Properties measured include Poisson’s ratio, compressive stress, compressive strain, and Modulus of Elasticity. ASTM D3518 establishes the in-plane shear response of polymer matrix composite materials ...

Shear stress-strain curve (left) and corresponding viscosity-stress curve (right) for materials with and without a yield stress. Stress Growth Unlike the stress ramp test where a steadily increasing ...

Because the average shear stress is used in the shear modulus calculation, the average shear strain between the notch tips, γ ave, also must be used to obtain the correct shear modulus. When ...

Dynamic shear rheometer. Dynamic rheology uses the same types of geometries as rotary rheometers in its analysis. In this case, the load is sinusoidally varying, and either shear stress or strain is ...
