Seminar on "Constitutive Modelling With Emphasis On Residual Stresses & Damage with Applications to Soft tissues and Cord-rubber Composites (Tyres & Air springs)"
Speaker: Dr. Niraj Kumar Jha.
Title: Constitutive Modelling With Emphasis On Residual Stresses & Damage with Applications to Soft tissues and Cord-rubber Composites (Tyres & Air springs)
The computational methods to assess the durability of a cord-reinforced structure will be explained. Damage mechanics approach will be used to explain the various failure modes, such as debonding, rubber matrix damage, etc.. Apart from the constitutive modelling, an invariant based approach to incorporate residual stresses in the material model will be discussed.
Speaker Bio: Dr. Niraj completed his under-graduation from NIT Tiruchirappalli. He worked at MSIL in the research and development center for more than 3 years before he went to pursue Master's in Computational mechanics and Ph.D. from Leibniz University of Hannover (TU9). His doctoral thesis develops the constitutive modelling framework for dealing with damage mechanisms for the cord-reinforced air spring systems.
