Characterization of magnesium spot welds under tensile and cyclic loadings
Behravesh, Seyed Behzad; Jahed, Hamid; Lambert, Steve (Elsevier, 2011-12-01)Resistance spot welds of a magnesium alloy were characterized in terms of microstructure, hardness and monotonic and cyclic properties. Microstructural features in base metal and different zones in the weld region were ... -
Development of a Fuzzy Slip Control System for Electric Vehicles with In-wheel Motors
Jalali, Kiumars; Uchida, Thomas; McPhee, John; Lambert, Steve (SAE International, 2012-04-16)A two-passenger all-wheel drive urban electric vehicle (AUTO21EV) with four direct-drive in-wheel motors and an active steering system has been designed and developed at the University of Waterloo. A novel fuzzy slip control ... -
Development of a Path-following and a Speed Control Driver Model for an Electric Vehicle
Jalali, Kiumars; Lambert, Steve; McPhee, John (SAE International, 2012-04-16)A two-passenger all-wheel-drive urban electric vehicle (AUTO21EV) with four in-wheel motors and an active steering system has been designed and developed at the University of Waterloo. In order to evaluate the handling and ... -
Development of an Advanced Fuzzy Active Steering Controller and a Novel Method to Tune the Fuzzy Controller
Jalali, Kiumars; Uchida, Thomas; McPhee, John; Lambert, Steve (SAE International, 2013-04-08)A two-passenger, all-wheel-drive urban electric vehicle (AUTO21EV) with four direct-drive in-wheel motors has been designed and developed at the University of Waterloo. An advanced genetic-fuzzy active steering controller ... -
Development of an Advanced Torque Vectoring Control System for an Electric Vehicle with In-Wheel Motors using Soft Computing Techniques
Jalali, Kiumars; Uchida, Thomas; Lambert, Steve; McPhee, John (SAE International, 2013-04-08)A two-passenger, all-wheel-drive urban electric vehicle (AUTO21EV) with four direct-drive in-wheel motors has been designed and developed at the University of Waterloo. A 14-degree-of-freedom model of this vehicle has been ... -
Development of an Integrated Control Strategy Consisting of an Advanced Torque Vectoring Controller and a Genetic Fuzzy Active Steering Controller
Jalali, Kiumars; Uchida, Thomas; McPhee, John; Lambert, Steve (SAE International, 2013-04-08)The optimum driving dynamics can be achieved only when the tire forces on all four wheels and in all three coordinate directions are monitored and controlled precisely. This advanced level of control is possible only when ... -
Fatigue characterization and modeling of AZ31B magnesium alloy spot-welds
Behravesh, Seyed Behzad; Jahed, Hamid; Lambert, Steve (Elsevier, 2014-07-01)Cyclic behavior of AZ31B spot-welds was studied using different specimen configurations, and compared with steel and aluminum spot-welds. Fatigue strength of magnesium spot-welds was similar to aluminum and less than steel. ... -
A Lagrangian model for hardening behaviour of materials at finite deformation based on the right plastic stretch tensor
Eshraghi, Amin; Jahed, Hamid; Lambert, Steve (Elsevier, 2010-05-01)In this paper a modified multiplicative decomposition of the right stretch tensor is proposed and used for finite deformation elastoplastic analysis of hardening materials. The total symmetric right stretch tensor is ...
