Thermoplastic matrix polymer composite materials have gained considerable attention in various applications as a result of their good versatility, durability, corrosion and wear resistance, rigidity, high dimensional stability, high ductility, lightweight, and ease of processability. High-density polyethylene (HDPE) is one of the most versatile and...

The European automotive sector is under pressure to transform into a zero net emission industry. This involves lightweight, highly efficient vehicles, but also zero emission structural materials. At the same time, a steel industry with automotion as its main customer faces a similar conundrum; it is only natural that this synergy is explored. One o...

The valorization of waste is an excellent way to protect the environment. This study focuses on waste consisting of cement that has hardened before use. The goal of this study is to determine the conditions under which these can be valorized in concrete. These wastes are used as aggregates, referred to as Hardened Cement Aggregates (HCA). First, th...

The global environmental protection legislations, desire for cost-saving and weight reduction, and depleting petroleum-based raw materials have been the driving force behind the adoption of cellulosic fibres/particulates as reinforcing fillers and materials in polymer-based composites for diverse applications in these modern days. Natural fibres/pa...

This study delves into the characteristics of a water jet impacting a stationary target, employing Computational Fluid Dynamics (CFD) simulations conducted with ABAQUS/CFD 6.14. Inspired by an orthogonal cutting configuration of a Ti6AL4V alloy during high-pressure water jet-assisted machining, the paper investigates the effect of nozzle inclinatio...

The aim of this study is to develop a finite element model of metal cutting that includes fluid structure interaction. The proposed model is used to improve the physical comprehension of the chip formation during cryogenic assisted machining. This is performed based on the coupled-Eulerian-Lagrangian formulation. An algorithm is also developed to e...

This paper deals with the approximation of the dynamics of two fluids having non-matching densities and viscosities. The modeling involves the coupling of the Allen-Cahn equation with the time-dependent Navier-Stokes equations. The Allen-Cahn equation describes the evolution of a scalar order parameter that assumes two distinct values in different ...

The primary purpose of this study is to assess excavated soil rich in limestone for its use as a raw material in manufacturing Compressed and Stabilized Earth Blocks (CSEBS). Valorization of cut excavation is a promising solution to reduce the strain on natural resources, which aligns with sustainable development goals. The identification of raw ma...

Smoothing curves have been used in computer aided design software for years. This is the reason why machinists very early wondered about the possibilities of creating toolpaths directly generated from this type of mathematical curves. In addition, in recent research work, we have shown that the non-uniform rational Bspline interpolation is the most...
