Sensitivities of Two-Dimensional Fracture Problems to the Near-tip Mesh Parameters
Source abstract
Abstract
Using the displacement correlation technique, near-tip mesh-parameter sensitivity studies are performed for cracks that cover most basic two-dimensional load-controlled problems. Stress intensity factors computed from two different mesh models for different settings of mesh parameters are compared with other solutions. The corresponding sensitivity graphs are plotted to visually see the parameters which affect results the most. Conclusions are drawn and settings of mesh parameter values are recommended.
