New Shear Lock Free Finite element
Dear All,
New algorithm based on Newton-Raphson method
A new numerical algorithm has been developed in this research work to reduce computational time.
New shear lock free finite elements with arbitrary higher order derivative
A set of highly efficient and shear lock free finite elements based on Timoshenko beam and Reissner-Mindlin plate theories has been developed for the analysis of thin and thick structures. These elements have arbitrary higher order derivatives and do not require any spcial integration scheme. All are isoparametric elements.

Analysis of beams and plates using shear lock free finite elements based on Timoshenko beam and Mindlin-Reissner plate theories
Simple finite elements based on Timoshenko beam and Mindlin plate theories have been developed for the analysis of thick and thin structures (beams and plates) using standard finite element procedure. These elements have 3 dof and a new concept, Convergence Factor, is introduced in the formuation to accelerate convergence keeping the number of elements constant. No shear correction factor is used and no shear lock problem is encountered.
