Sažetak
Although gears are, like most engineering structures, influenced by complex multiaxial stresses that arise from loading and geometry, simple specimens that are subjected to uniaxial states of stress are usually used in laboratory testing for obtaining material behavior and fatigue characterization, . The data recorded through these tests are used for material behavior estimation within the range of elastic-plastic deformations. In this paper, the material behavior in low–cycle fatigue regime is described by complex material model that combines isotropic and kinematic hardening with mechanics of material damage. It is used to simulate elastic-plastic material behavior and damage nucleation and accumulation. Numerical modeling of fatigue damage can provide better fatigue life estimation of gears, focusing on the crack initiation period.
