چکیده
Composite moulds constitute an attractive alternative to classical metallic when used for components fabricated by processes such as Resin Transfer Moulding (RTM). However, there are many factors that have be accounted if a correct design of the is sought after. In this paper, Finite Element Method (FEM) help in mould. To do so, thermo-electrical simulation has been performed through MSC-Marc preheating phase order ensure mould able heated, Joule’s effect, according thermal cycle specified under operating conditions. Mean temperatures 120 °C and 100 predicted lower upper semi-mould parts, respectively. Additionally, thermo-electrical-mechanical calculation completed with calculate tensile state along system during stage. For filling phase, process itself simulated RTM-Worx. Both uniform- non-uniform temperature distribution approaches assess resulting effect. It found piece software cannot model dependency resin numerical trick must applied second case overcome it. Results very dependent on approach, time being 73% greater modelling distribution. The behaviour stage, consequence pressure, also proved specific mechanical analysis conducted MSC-Marc. Finally, thermo-elastic response curing stage numerically assessed. This made MSC-Marc, paying special attention exothermic reaction takes place. sake accuracy, user subroutine include laws used. Material properties employed described detail following modified version Scott model, extracted from experiments. All these detailed calculations cornerstone designing composite unveiled some capabilities were missed commercial codes employed. Future versions will deal weak points but, whole, shown appropriate tool helping moulds.

FEM Based Modeling in COMSOL Multiphysics and Design of Control of Distributed Parameter Systems
This paper presents a finite element method based modeling and design of control for distributed parameter systems. First, models of distributed parameter systems in the form of lumped-input/distributed-output systems and structure of control loop are introduced. Next, modeling of temperature fields of the casting die as distributed parameter systems in preheating process is performed in COMSOL...
متن کاملUsing Graphics Cards for Quantized FEM Computations
Graphics cards exercise increasingly more computing power and are highly optimized for high data transfer volumes. In contrast typical workstations perform badly when data exceeds their processor caches. Performance of scientific computations very often is wrecked by this deficiency. Here we present a novel approach by shifting the computational load from the CPU to the graphics card. We repres...
