We present a partition of unity-enriched element-free Galerkin method for thermoelastic twodimensional crack problems. Therefore, the displacement field is enriched by the step enrichment. In the vicinity of the crack tip, the asymptotic branch enrichment functions commonly used in linear elastic fracture mechanics are employed. The same enrichment strategy is employed for the temperature field. Level set functions are used in order to model the crack surface. The accuracy of the method is demonstrated for three examples, one involves the crack propagation due to temperature and mixed traction-temperature loading conditions with complex curved crack paths.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
