Transfer learning enhanced physics informed neural network for phase-field modeling of fracture
Somdatta Goswami, Cosmin Anitescu, Souvik Chakraborty +1
We present a new physics informed neural network (PINN) algorithm for solving brittle fracture problems. While most of the PINN algorithms available in the literature minimize the…
Threshold shift method for reliability-based design optimization
Somdatta Goswami, Souvik Chakraborty, Rajib Chowdhury +1
We present a novel approach, referred to as the 'threshold shift method' (TSM), for reliability based design optimization (RBDO). The proposed approach is similar in spirit with th…
A Gaussian process latent force model for joint input-state estimation in linear structural systems
Rajdip Nayek, Souvik Chakraborty, Sriram Narasimhan
The problem of combined state and input estimation of linear structural systems based on measured responses and a priori knowledge of structural model is considered. A novel method…
