Modeling the Non-linear Viscoelastic Response of High Temperature Polyimides
Satish Karra, K. R. Rajagopal
A constitutive model is developed to predict the viscoelastic response of polyimide resins that are used in high temperature applications. This model is based on a thermodynamic fr…
On Maxwell fluid with relaxation time and viscosity depending on the pressure
Satish Karra, Vít Průša, K. R. Rajagopal
We study a variant of the well known Maxwell model for viscoelastic fluids, namely we consider the Maxwell fluid with viscosity and relaxation time depending on the pressure. Such…
A thermodynamic framework to develop rate-type models for fluids without instantaneous elasticity
Satish Karra, K. R. Rajagopal
In this paper, we apply the thermodynamic framework recently put into place by Rajagopal and co-workers, to develop rate-type models for viscoelastic fluids which do not possess in…
Development of three dimensional constitutive theories based on lower dimensional experimental data
Satish Karra, K. R. Rajagopal
Most three dimensional constitutive relations that have been developed to describe the behavior of bodies are correlated against one dimensional and two dimensional experiments. Wh…
Degradation and healing in a generalized neo-Hookean solid due to infusion of a fluid
Satish Karra, K. R. Rajagopal
The mechanical response and load bearing capacity of high performance polymer composites changes due to diffusion of a fluid, temperature, oxidation or the extent of the deformatio…
