Cyclic Characterisation and Plasticity Modelling of AM30 Magnesium Alloy Extrusion
Roostaei, Ali Asghar (University of Waterloo, 2017-08-14)Reducing fuel consumption and, thereby, greenhouse gas pollution has been the main thrust of lightweighting endeavours by transportation industries, particularly, automotive sector. Wrought magnesium alloys, being the ... -
Fatigue Life Prediction of an Automotive Chassis System with Combined Hardening Material Model
George, John K.; Gross, Daniel; Jahed, Hamid; Roostaei, Ali Asghar (Society of Automotive Engineers, 2016-04-05)The choice of an appropriate material model with parameters derived from testing and proper modeling of stress-strain response during cyclic loading are the critical steps for accurate fatigue-life prediction of complex ... -
Multiaxial cyclic behaviour and fatigue modelling of AM30 Mg alloy extrusion
Roostaei, Ali Asghar; Jahed, Hamid (Elsevier, 2017-04-01)Multiaxial fatigue characteristics of AM30 Mg alloy extrusion are studied through fully-reversed strain controlled cyclic experiments including pure torsional and combined axial-torsional at 0, 45 and 90 phase angle shifts. ... -
Role of loading direction on cyclic behaviour characteristics of AM30 extrusion and its fatigue damage modelling
Roostaei, Ali Asghar; Jahed, Hamid (Elsevier, 2017-07-18)Anisotropic fatigue and cyclic behaviour of AM30 Mg alloy extrusion is investigated by performing fully-reversed strain-controlled tension-compression cyclic tests at strain amplitudes between 0.3% and 2.3%, along extrusion ...
