Before running a simulation, you must define the physical characteristics of the crack: Crack Patran Nastran
Once the solver finishes, you return to Patran to interpret the results: : Using singular elements (quarter-point nodes) at the
: Visualizing "Damage" or "Log of Life" to see which parts of the structure will fail first. Crack Patran Nastran
The process of simulating crack propagation or fatigue life generally follows these three stages: 1. Pre-Processing in MSC Patran
