The behavior of laminated composite skew plates under different temperature variations is an important phenomena which was explored in this study. For modelling of laminated composite skew plate the suitable parabolic variation of transverse shear variation was considered. The skew effect was incorporated with transformation matrix detailed in the manuscript. Due to parabolic variation of transverse shear considered the need of shear correction factor was circumvented in present work. The different type of temperature variations were considered in the present work. The parametric variations of skew angle, plate thickness etc. were varied to study the temperature variation behavior on laminated composite skew plate. The authors developed the FORTRAN code for the finite element formulation of present mathematical model along with temperature variations incorporations. Nine node isoparametric finite elements were used in the present FE formulation. Top and bottom zero transverse shear stresses were implied in present formulations to calculate unknown parameters. The developed model 2D allowed prediction of results close to 3D solution. The presented method work results are in close resemblance with previously published results obtained by other methods.

In present work thermal and moisture concentration effects on laminated composite hypars is explored. Third degree thickness coordinate is considered in plane displacement variables. The twist curvatures of hypars is considered in present analysis. The shear correction factor is eliminated due to actual representation of transverse shear in present work. Imposition of nil transverse shear stress conditions at top and bottom of the surface of hypars is done mathematically. Finite element (FE) formulation of present mathematical model is done using a nine noded curved isoparametric element with seven unknowns at each node. FE formulation is coded in FORTRAN. The comparison study of present work is found to be consistent with previous published works by different methods. The parametric study is done by varying different parameters like moisture concentration, temperature variations, and boundary conditions. [ABSTRACT FROM AUTHOR]
