“…The combination of these two models usually provides a faster solution with respect to the entire detailed model to achieve accurate results within the RoI. This strategy has been widely used to solve problems in different engineering fields including structural mechanics, 6,7 electromagnetics, 8,9 and thermofluid dynamics. 10,11 In this paper, the application of the submodeling approach to FE wear predictions is investigated.…”

Summary Finite element simulation is a powerful tool to study and predict the wear behavior of different mechanical systems. However, the high computational cost required to obtain accurate numerical solutions is a crucial aspect especially for large and complex models. The present study proposes a possible solution to overcome this limitation by exploiting the potentiality of the submodeling technique, whose application to wear problem is still rare in the literature. A global‐local approach for wear analysis is presented and validated for a simple pin‐on‐disk wear test. In a preliminary step, different submodeling techniques were implemented and compared. They differed for the quantity (nodal forces and/or displacements) transferred from the global model to the local one. Numerical models have been developed in Ansys® mechanical APDL using its new wear simulation and mesh smoothing routines. Results suggest that the proposed strategy can significantly reduce the computational cost of finite element wear models. Some interesting points on the use of submodeling in contact problems are also discussed.

“…It is necessary to note that now it is successfully used in industrial curing processes [ 13 , 14 , 15 , 16 ], and microwave-assisted pultrusion processes are analyzed only experimentally [ 17 , 18 , 19 ]. A limited number of studies [ 20 , 21 ] published recently on the simulation aspects of microwave-assisted pultrusion processes have slowed down their development. For this reason, new, reliable electromagnetic-thermo-chemical finite element models and algorithms were developed in this study by using the general-purpose finite element software ANSYS.…”

Pultrusion is a technological process in which fibers impregnated with resin move through the heated die and solidify into a composite profile with a constant cross section, as in the metallic die. The effectiveness and productivity of conventional pultrusion processes, preserving the quality of pultruded profiles, could be improved by process optimization or by the application of new, effective heating sources instead of electrical resistances with high heat losses. Due to the large dimension of the numerical problem and multiple iterations applied for the solution of government equations, an optimization methodology was developed, using the method of experimental design and the response surface technique. To develop microwave-assisted pultrusion processes, as well as pultrusion tooling design and process control, new effective electromagnetic-thermo-chemical finite element models and algorithms were developed by using general-purpose finite element software that results in considerable savings in development time and costs and makes available various modeling features of the finite element packages. The effectiveness and productivity of the optimized conventional pultrusion processes and the developed microwave-assisted pultrusion processes are estimated in comparison with the real pultrusion processes used in laboratory and industrial shops.

The main purpose of this study is an experimental investigation and comparison of the mechanical properties of pultruded glass fibre reinforced polymer composite based on polyester and vinylester resin. For this purpose, the specimens were cut from the walls of square tube pultruded profile along to the fibres direction. The mechanical properties of the pultruded composite such as ultimate tensile strength and ultimate bending strength, tensile modulus and flexural modulus were obtained. It was observed that using of vinyl ester resin in pultruded composite instead of polyester resin enhanced the ultimate tensile and flexural strength from ~13% to ~24% in dependence of composite specimen’s thickness.
