In this paper, a two-dimensional computational model is proposed for predicting the

initiation position and propagation path of subsurface crack of spur gear tooth flank. In

order to simulate the contact of ...

This study investigates the rate and path of fatigue crack growth under mixed mode I/II loading in

the presence of tensile and compressive stresses. Compact tension shear (CTS) specimens made of

42CrMo4 steel ...

Contact stress is an important problem in industry. This is a problem that in the first attention may be don’t appears, but disregard of these stresses cause a lot of damages in machines. These stresses occur at locations ...

Spalling is a phenomenon that occurs on gear tooth flanks by contact

fatigue loading. Contact loading results to shear stress in tooth below the surface.

In repeating contact loading, shear stress also repeats. ...
