WebDec 12, 2015 · In addition, 36 shear-compression tests were carried out under cyclic loads to emphasize the influence of various loads on the shear-compression behavior of DSM. The results showed that the Mohr-Coulomb friction law adequately represents the failure of dry joints at moderate stress levels, and the varying friction coefficients under different ... WebShear is defined as force generated when the skin is moved against a fixed surface such as a bony skeleton moving in an opposite direction to the surface skin. It is important to note that any pressure injury that is accompanied by other forces (shear and friction) will result in a debilitating tissue injury 3 .
