mixed mode fracture; phase field model

We present the first mixed mode phase-field model of ductile fracture. The contribution of crack opening and shearing deformations to the propagation of a crack is expressed by introducing two phase fields. Constitutive relations are then introduced to couple and distinguish these phase fields. Special attention is given to the maximum shear stress and its effect on the development of fractures. The proposed model is validated by tensile testing experiments found in the literature on Al 2024 T-351.

Funded Ph.D. positions in Metal Forming and Additive Manufacturing in Southern Methodist University(Dallas, TX)

Submitted by LinRunning on Mon, 11/28/2022 - 02:47

Prof. Wei TONG of Southern Methodist University is looking to recruit several Ph.D. students in the fall of 2023 to work on anisotropic plasticity, metal forming, laser materials processing, and additive manufacturing research projects at Research Center for Advanced Manufacturing (RCAM). Good background in solid mechanics, experimental technique, or finite element modeling is highly welcome. The potential candidate should hold an M.S. degree in mechanical, aerospace engineering, solid, engineering mechanics, or other related majors.
