Creep and Elastic-plastic Behavior for Automobile Engine Cylinder Block Al Alloy 319
Based on NAFEMS standard, the non-proportional load was loaded on Al alloy. The aluminum alloy 319nonlinear material model for 319 thick-walled car engine cylinder was built, and nonlinear stress strain, creep and elastic-plastic behaviors of engine aluminum alloy 319 were simulated. The results show that the elastic-plastic and creep model created is used to calculate the cylinder wall creep curves, which is in good agreement with the target data using NAFEMS standard. This indicates that NAFEMS benchmarks model can predict well the time history of the equivalent creep strain in the inner surface of the engine cylinder.
