Abstract A post-processing scheme is presented
to accurately determine transverse shear and normal
stresses in composite panels undergoing geometrically
nonlinear deformation under dynamic
loading conditions. Transverse stresses are assumed
through thickness at a point of interest and
are recovered via a one-dimensional finite element
method. The finite element method is based
on the least square functional of the error in the
equilibrium equation along the thickness direction
and utilizes the in-plane stresses and resultant
transverse shear forces per unit length obtained
by a shell element analysis. Numerical results
demonstrate that, with minimal addition of
computational efforts, the present post-processing
approach can… More >
