If the Poisson’s ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...

Highly developed universal testing machines and custom testing systems are of use in running tests and the determination of properties, for example breaking strength, ductility, elongation, fracture ...

This dual experimental-numerical approach provides a rare, holistic view of bonded joint performance under ballistic loading, ...

A hydrogel engineered with cell-like particles mimicking skin tissue achieves 99.9% compressibility and ultralow energy loss ...

Strain gauge sensors measure the strain (displacement) of an object under an applied force. When they are adhesively attached to the object under stress (an applied force), they deform with the object ...

NORWOOD, Mass.—Instron Corp., a manufacturer of testing equipment for an array of different materials, is addressing both the pain and the strain points of lab evaluations with the launch of its AVE3 ...

The offset shear strength is the shear stress endured by a material at the intersection of the shear stress versus the engineering shear strain curve, with a line parallel to a defined modulus and ...
