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.

How is it possible to obtain the transverse shear stresses correctly, not constant, by Reissner Mindlin theory?
Equilibrium equation would be the first solution, but, once the second derivatives of bilinear shape functions are zero, no results is appeared.
Thanks in advance for any help!
The 2014 Nathan M. Newmark Medal was awarded to Professor Herbert A. Mang at the annual ASCE Structures Conference, which took place in Boston, April 3–5, 2014. Professor Mang was awarded the Newmark Medal for his outstanding research contributions in the area of nonlinear continuum and computational mechanics that clarified the cause of collapse of important concrete structures and quantified the influence of the initial post buckling behavior of metallic structures.
Dear friends,
Could anyone be kind to share some comments on my interesting results? It is my first time to post a topic, hope to communicate more with the members here.

In spite of worldwide research, carbon nanotubes (CNTs) still have not fully realized their
original promise as ideal reinforcements for composite materials due to a number of
challenging issues such as weak interface, poor dispersion, misalignment and lack of optimized
design. Here we propose a bio-inspired structure of CNT bundles with controllable
crosslink density and staggered pattern of organization that mimic the architecture of
