A generic mixed FE-SPH method to address hydro-mechanical coupling in liquid composite moulding processes

Efficient stochastic simulation approach for RTM process with random fibrous permeability

“…In order to design the appropriate stiffness and closing force of the mold for the targeted thickness or fiber volume fraction [22,23], the range of resin pressure magnitude needs to be known. However, without taking into account the uncertainty in pressure field, the maximal pressure magnitude may be underestimated by traditional simulation codes, which increases the risk of preform deformation and mold deflection.…”

Numerical simulation of flow processes in composites manufacturing

“…Recently, mesh-free method such as smoothed particle hydrodynamics was adopted to simulate the resin flow and preform deformation (Comas-Carddona et al, 2005). In this method, each particle representing a small finite volume of resin moves along the negative pressure gradient, and there is no need to regenerate the mesh through the calculation.…”

Numerical Study of Liquid Composite Molding Using a Smoothed Particle Hydrodynamics Method

“…Meshless methods, such as the lattice Boltzmann and smoothed particle hydrodynamics (SPH) method, have emerged as novel modeling tools in this area due to their ability to handle moving interface with large deformation without the need of interface tracking (Trochu et al, 2006;Cleary et al, 2007;Comas-Cardona et al, 2005). Sawley et al (1999) developed a pore-scale SPH model to study resin flow through the pores of a porous medium, and investigated the effect of the edge flow.…”

“…Although the model gave good qualitative results, it is difficult to simulate the filling process at a mold scale using the pore-scale simulation. Comas-Cardona et al (2005) used coupled FE-SPH to simulate the hydromechanical coupling process. In this study, we conducted 2D simulations of LCM using the SPH method.…”
