The Study on Fatigue Crack Propagation in Metal Using Finite Element Analysis
Fatigue in materials is caused by repeated loading and unloading cycles below the ultimate strength of a material. Fatigue tests are expensive since they required a lot of time consuming. Simulation of fatigue crack propagation using commercial software can reduce the costs related to time. The p...

| description | Fatigue in materials is caused by repeated loading and unloading cycles below the
ultimate strength of a material. Fatigue tests are expensive since they required a lot of time
consuming. Simulation of fatigue crack propagation using commercial software can reduce the
costs related to time. The purpose of this study is to compare the fatigue crack propagation in metal
under variable and constant amplitude loading. A standard size of aluminum cast alloy specimen
according to ASTM E647 document was modelled using a pre-processor and it was later being
analysed. In another aspect, strain gauges were attached to an engine mounting bracket and
connected to the data acquisition set in order to capture the actual strain signals when an automobile
was driven on to different road conditions. For the simulation purpose, a constant amplitude loading
was then derived from a variable amplitude loading obtained from the data capturing process. The
related parameters on between different road conditions, variable and constant amplitude loadings
and crack propagation rate were presented. The relationship between those parameters were finally
correlated and discussed. |
