Three-dimensional numerical analysis of reflective cracks ...

The analysis of reflective cracking involves all modes of fracturing i.e., Mode I (opening), Mode II (shearing), and Mode III (tearing) [61] and thus 3-D models are required. The need for true 3-D modeling of reflective cracking complicates the development of computational models using standard finite element methods.
