Crack-tip stress evaluation requires special treatments in the frame of classical elasticity theory for characterizing fatigue crack growth behavior. In previous studies, modified finite element methods have been used to remedy infinite stresses predicted by the classical elasticity theory at the...

The dynamic response of osseointegrated implant systems can be used to evaluate the condition of the bone-implant interface (BII) and implant stability. The primary objective of this work is to develop a simplified dynamic 1D finite element (FE) model of the OPL transfemoral amputation (TFA)...

Ring vibration analysis is more challenging than straight beams analysis. In straight beams, the structural deformations depend on rotational and translational displacements; however, in rings, in addition to these, they also depend on the coupled tangential displacement caused by the curvature...
