Tensile Deformation and Crack Propagation in FCC Copper

Department of Materials Science & Engineering, University of Tennessee

These structures were created by Elizabeth Heon in the Department of Materials Science and Engineering, University of Tennessee

In this project tensile deformation of FCC copper was first simulated using both the embedded atom method (EAM) and Lennard-Jones potentials Tensile deformation of a pre-cracked speciment was then simulated in order to study crack propagation. In the above animation tensile deformaiton of a pre-cracked Cu specimen is seen. Abnormal necking behavior is observed, likely because this simulation was run in the NPT ensemble which imposes a constant volume condition on the system. 1
