Woven thermoplastic composite forming simulation with solid-shell element method

Forming simulation of a thermoplastic commingled woven textile on a double dome

This paper presents thermoforming experiments and FE simulations of a commingled glass-PP woven composite on a double dome geometry, with the aim of assessing the correspondence of predicted and experimental shear angles. Large local deformations especially in-plane shear, i.e. relative rotation between the two yarn families – occur when draping a textile on a three dimensional part and eventua...

Tensile behavior simulation of woven fabric with different weave pattern based on finite element method

Stochastic simulation of woven composites forming

A stochastic forming simulation procedure is developed and implemented to investigate the effect of geometric variability in pre-impregnated woven textiles on manufacturing. Image analysis is used to characterise variability in tow directions and unit cell size in a pre-impregnated carbon/epoxy satin weave textile. It is found that variab ility in tow orientations is significant, whereas variab...

Simulation of 3d Rtm Process Using Solid Shell Element

Introduction In the era of process modeling of composite materials, 3D simulation of manufacturing processes is desirable considering the manufacturing trend where parts became more complex leading to complex 3D stress-strain states. Moreover, coupling of sub-processes that are happening simultaneously such as macro-scale preform processes, flow advancement and solid and fluid interaction requi...

Numerical Analysis of Delamination Buckling in Composite Cylindrical Shell under Uniform External Pressure: Cohesive Element Method

Nowadays, due to high ratio of strength to weight, composite cylindrical shells are extensively used in a great variety of different industrial applications and under different cases of loads. In this study, the buckling of composite cylindrical shells was examined under uniform external pressure. The buckling analysis of composite cylindrical shells was first done by using theoretical relation...
