The aim of this paper is to develop a model allowing fast first approximate estimation the elastic–plastic stress wave propagation caused by laser impact and resulting residual field. We start modeling propagation, adopting 1D uniaxial modeling, reducing behavior specimen axis impact, excluding any edge effects edges spot. plastic strain field from can in turn be used compute stresses, making u...

This study provides an approach to predict the springback phenomenon during post-solidification cooling in a functionally graded hybrid composite cylindrical shell with a transverse isotropic structure. Here, the material properties are given with a general parabolic power-law function. During the theoretical analysis, an appropriate transformation is introduced in the equilibrium equation, whi...

Abstract This study was conducted to assess the potential of charcoal and activated derived Polyethylene Terephthalate (PET) as adsorbent through experiment chromium hexavalent [Cr (VI)] removal from aqueous solution. The aims investigate optimum adsorption conditions for Cr (VI) in solution under diverse operating conditions, namely pH, contact time, agitation speed, dosage, initial concentrat...

Plastics are a precious, versatile set of materials. The accumulation plastic waste threatens the environment. Recycling can produce many new products. opportunities for using create pressure strategy to develop or improve current management systems reduce negative impact on humans, fauna and flora. objective this review paper is consider an opportunity recycle plastic; convert into sand bricks...
