Jinlei Shen and Preetam Tarafder, both graduate students in the Department of Civil and Systems Engineering, recently were awarded first and second place in the EMI 2021: Modeling Inelasticity & Multiscale Behavior Student Paper Competition.
Jinlei’s paper, titled “Microstructure-informed Fatigue Crack Nucleation Prediction for Dual Phase Ti-64 Alloys using Experimentally validated Parametrically Homogenized Constitutive Models,” received the award for first place. The paper showcases Jinlei’s work in developing the experimentally validated Parametrically Homogenized Constitutive Model (PHCM) and Parametrically Homogenized Crack Nucleation Model (PHCNM) to predict fatigue crack nucleation life in titanium alloys effectively.
Preetam’s paper, which took second place in the competition, is titled “A finite deformation cohesive zone enhanced phase field model for crack propagation in multi-phase microstructures.” It showcases his development of a model for simulating interfacial decohesion and crack evolution in multi-phase elastic materials undergoing finite deformation.
The competition was sponsored by the EMI Modeling Inelasticity & Multiscale Behavior (MIMB) Committee. Winners were selected after all papers were reviewed by the committee and the authors of the top five papers gave presentations about their research in a special session at the 2021 EMI Conference.
Both students are advised by Prof. Somnath Ghosh.
