Derivation, characterization, and application of complete orthonormal sequences for representing general three-dimensional states of residual stress
Sankalp Tiwari, Eliot Fried
Residual stresses are self-equilibrated stresses on unloaded bodies. Owing to their complex origins, it is useful to develop functions that can be linearly combined to represent an…

Solution of planar elastic stress problems using stress basis functions
Sankalp Tiwari, Anindya Chatterjee
The use of global displacement basis functions to solve boundary-value problems in linear elasticity is well established. No prior work uses a global stress tensor basis for such s…
