TL;DR: In this article, a numerical study using the finite element method has been carried out to investigate the response of composite shells with cutouts subjected to internal pressure and axial compression and the CAE package ABAQUS has been employed for the analysis.

TL;DR: In this paper, a series of finite element analyses on the delaminated composite cylindrical shells subject to combined axial compression and pressure are carried out varying the delamination thickness and length, material properties and stacking sequence.

TL;DR: In this paper, stress analysis of drillstring threaded connections under axial, bending and torsion loadings has been carried out using the finite element method in order to determine the regions of highest stress concentration.

TL;DR: In this article, a finite element model was developed to study global, local and mixed mode buckling behavior of composite plates with embedded delaminations under compression, and the global modelling results were compared with corresponding experimental results, and it was observed that the local buckling mode was highly influenced by the laminate stacking sequence.

TL;DR: In this article, the authors deal with the computational modelling of delamination in isotropic and laminated composite cylindrical shells and show that through-the-thickness delamination can be modelled and analyzed effectively without requiring a great deal of computing time and memory.
