Current Research Work

  • ALE Formulation of Nonlinear Problems: Our developed ALE formulation and in-house ALE program is capable of handling large strain quasi static and dynamic problems in plasticity coupled with thermal effects. Extending the formulation to dynamic fracture mechanics and full scale dynamic problems is undergoing.
  • Crack Detection and Crack Propagation: The objective is to provide industry with combined experimental and numerical solution procedure for crack detection and crack propagation monitoring in rotating components. The emphasis is placed on the practical aspects of identifying flaw parameters and supplying estimates about critical size and remaining safe life in operation.
  • Modeling of Controlled Cooling of Steel on Run-Out Table: Run-out table cooling following hot rolling is the crucial step in determining the final mechanical properties of the steel. The objective of this work is to provide participating companies with a tool to design unique run-out table processing paths that control the phase transformation of new steels and provide optimum mechanical properties.
  • Behavior of Piezoelectric Actuators: Static and dynamic behavior of piezoelectric actuators used in fuel injectors are studied. The project involves experimental electric fatigue tests under various operating conditions and development of finite element models to predict the behavior.
