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
