G. Ravichandran, Director of GALCIT

G. Ravichandran

Guruswami Ravichandran, Professor of Aeronautics and Mechanical Engineering, 1990–present; John E. Goode, Jr., Professor, 2005–present. Experimentalist whose work has covered dynamic response characteristics of materials; thermodynamics of the energy conversion process in large deformation and rate dependent plasticity phenomena. In deviating from the standard test routines associated with uniaxial compression behavior, his interest has centered on generating multiaxial stress states dynamically using high-strain rates, with applications to impact and penetration problems in metals, ceramics, and heterogeneous materials including composites and sandwich structures. Experimental development (with Rosakis) of highspeed thermography to follow the evolution of energy conversion at the tips of rapidly moving cracks and in the evolution of shear bands. Time-dependent and multiaxial behavior of amorphous metals and metallic glasses. Investigation of large deformation elastostriction behavior in materials that can potentially be used as actuators. Investigation of 3D deformation in biomaterials and cell motility.

Research Overview

Professor Ravichandran focuses on deformation and failure of materials, micro/nano mechanics, wave propagation, composites, active materials, biomaterials and cell mechanics, and experimental mechanics.

Space-Related Research

Mechanics of light-weight materials; active materials with large strain actuation; space structures.
