Hamidreza Jahedmotlagh

Hamid Jahed is a Professor in the Mechanical and Mechatronics Engineering Department. He is also the Associate Chair for Graduate Studies and Director of the Fatigue and Stress Analysis Laboratory at the University of Waterloo.

Professor Jahed’s research interests lie in the mutiscale characterization, modelling, and life enhancement of lightweight materials under cyclic loading, and the development of robust methods in cyclic plasticity analysis. His research is funded by different funding agencies including NSERC, NSERC APC, CFI, ORF, IAMI, AUTO21.

Work in the Fatigue and Stress Analysis Laboratory focuses on fatigue and fracture properties of materials and weldments under uniaxial and multi-axial loads, development of cyclic plasticity and life prediction models for anisotropic materials, residual stress formations and measurements, and cold spray coating technology. Other areas of work include the study and development of robust and efficient methods for durability analysis and their applications to Computer-Aided Engineering (CAE) design.

Professor Jahed has received a number of awards including Faculty of Engineering and Sandford Fleming Foundation Teaching Excellence Award, and Engineering Research Excellence Award.
