Ongoing Project
Title: Numerical failure analysis of structures at different stress-state and subjected to different strain-rate using the finite element methods
Funding Agency: Research Initiation Grant, BITS-Pilani, Pilani Campus, Rajasthan
Amount: 2 Lakhs
Duration: 2019-2021
Objective: Classical fracture mechanics approaches have limitations for transferibility of fracture obtained data from simple laboratory to the actual working environment. Hence, significant effort has been spent towards development of phenomenological fracture models that can simulate the characteristic features of the failure process such as Johnson-Cook fracture model (J-C), Gurson-Tvergaard-Needleman (GTN), Cohesive Zone Model, Xue-Wierzbicki model (X-W), CrachFEM. In the recent time Extended Finite Element Method (X-FEM) has gained much popularity among fracture professionals.
Damage detection and life estimation of structural components using commercially available finite elements packages such as ABAQUS and ANSYS is the objective of the project. Failure analysis of the structure subjected different stress-state and strain-rate using various damage model available in commercially available finite element packages will be the center of discussion. Commercially available finite elements packages ABAQUS will be used for analysis of structural materials such as metal, composites and bio-materials.
