A combined isotropic, kinematic and distortional hardening model for aluminum and steels under complex strain-path changes
(Journal article; Peer reviewed, 2018)In this work, a new model is proposed for predicting stress transients caused by strain path changes. The model is formulated in stress space, where a second order tensor, i.e., the microstructure stress deviator, is used ... -
Assessment of advanced Taylor models, the Taylor factor and yield-surface exponent for FCC metals
(Journal article; Peer reviewed, 2019)High-resolution crystal plasticity-finite element method (CPFEM) simulations are performed to provide new reference values of the Taylor factor M and the isotropic yield surface exponent for high stacking fault energy ... -
Bauschinger effect modelled by yield surface distortions
(Journal article; Peer reviewed, 2019)A model for distorting the yield surface by flattening the part in the reverse of the loading direction, is suggested. As the basis for the distortion, the model applies a pair of second-order back-stress tensors of similar ... -
Experimental characterization and modeling of aluminum alloy AA3103 for complex single and double strain-path changes
(Journal article; Peer reviewed, 2018)The stress-strain behavior of the aluminum alloy AA3103 subjected to single and double strain-path changes (SPCs) is studied experimentally. The experimental program includes compression-tension, tension-tension, rolling-tension ... -
Multi-level modelling of mechanical anisotropy of commercial pure aluminium plate: Crystal plasticity models, advanced yield functions and parameter identification
(Journal article; Peer reviewed, 2015)The mechanical anisotropy of an AA1050 aluminium plate is studied by the use of five crystal plasticity models and two advanced yield functions. In-plane uniaxial tension properties of the plate were predicted by the ... -
Strain-path change induced transients in flow stress, work hardening and r-values in aluminum
(Journal article, 2015)Commercially pure aluminum with random texture was prestrained either by rolling or by uniaxial compression, and then tested in uniaxial tension to study the transients in flow stress, work hardening and r-value induced ...
