Learning constitutive relations from experiments: 1. PDE constrained optimization

Andrew Akerson, Aakila Rajan, Kaushik Bhattacharya

We propose a method to accurately and efficiently identify the constitutive behavior of complex materials through full-field observations. We formulate the problem of inferring con…

Comprehensive Study of $k$ -essence Model: Dynamical System Analysis and Observational Constraints from Latest Type Ia Supernova and BAO Observations

Saddam Hussain, Sarath Nelleri, Kaushik Bhattacharya

We constrain the parameters of the $k$ -essence scalar field model with inverse square and exponential potentials using data sets including Pantheon+SHOES and the Dark Energy Survey…
