Extended isogeometric analysis for dynamic fracture in multiphase piezoelectric/piezomagnetic composites

A dynamic extended isogeometric analysis (XIGA) is developed for transient fracture of cracked magnetoelectroelastic (MEE) solids under coupled electro-magneto-mechanical loading, taking the advantages of high order NURBS basis functions and enrichment methods. The extended dynamic fracture parameters are estimated through the electro-magneto-mechanical interaction integral. Numerical examples of electrically and magnetically impermeable cracks...
