Abstract
En 中文
• A novel three-dimensional Crack Element Method (CEM) is developed, incorporating an advanced element-splitting algorithm and a new formulation for computing the fracture energy release rate. • The 3D element-splitting algorithm enables element-wise crack growth, including crack branching, and approximates the displacement field of fractured elements using the Edge-based Smoothed Finite Element Method (ES-FEM). • The fracture energy release rate is evaluated based on the evolving topology of split elements, allowing for accurate and efficient tracking of crack propagation in 3D problems. • All 3D benchmark simulations leverage NVIDIA GPU acceleration, highlighting the method’s suitability for high-performance computing (HPC) in industrial settings.
