Finite element modelling of Indian plate

Abstract

One of the most challenging problems that earthquake engineers must resolve is the prediction of seismic activity and the estimation of the accompanying dangers. Numerous seismologists have proposed empirical equations as solutions to these problems. Since the process of establishing empirical equations is unpredictable, engineers have to develop mechanistic models to quantify seismic activity. Due to its simplicity, the finite element method, one of several numerical approaches, is frequently utilized in a number of fields and applications. Despite the Himalaya being considered a plate boundary and an active zone in Indian context, the seismicity database demonstrates that other regions of the Indian shield are sometimes experiencing seismic activity. The finite element method-based mechanistic models of the Indian plate are expected to simulate stress fields, which will measure the seismic potential of India's active zones. By examining the simulated stress field for various boundary conditions, geological circumstances, and rheological conditions, this study develops a finite element model for the Indian plate. The literature claims that these circumstances have an impact on the magnitude and direction of strains in the plate. The simulated stress field demarcates the seismically active regions of India, according to the numerical analysis of the models.
