This project under National Supercomputing Mission, India, will involve the development and implementation of new computational methods for the study of dynamic crack and friction problems.
Professor Ranjith Kunnath, Department of Mechanical Engineering, Mahindra University’s project under National Supercomputing Mission, India, will develop and implement new computational methods to study dynamic crack and friction problems. The boundary integral equation method is widely used for studying planar fracture problems. It is computationally more efficient than finite difference and finite element methods. However, it is also more specialised and is suitable only for limited geometries of the solids under study. In the present project, a spectral form of the boundary integral equation method is developed. It takes advantage of the numerical efficiency of the Fast Fourier Transform algorithm. The integral boundary equation is coupled with a constitutive law for the interface, such as a friction law or a cohesive law. Parallel codes will be developed that are suitable for CPU/GPU architectures.
