This paper presents a modified Biot’s model for describing the hydromechanical behaviour of Callovo-Oxfordian Argillite (COx) Claystone. The COx Claystone exhibits significant deformation during water desaturation/resaturation, and standard is unable to predict large shrinkage/swelling material. authors then introduced an additional swelling/shrinkage law simulate deformations upon changes in c...

In this paper, some molding process parameters such as injection time, packing time, packing pressure and process temperature etc. were optimized by the Computer Aided Engineering (CAE) simulation (Moldex 3D) for injection molding of a plastic lens. Some experimental trials were carried out for verifying of the CAE simulation results with checking of the lens shrinkage and birefringence etc. as...

We provide a derivation of the Föppl-von Kármán equations for the shape of and stresses in an elastic plate with residual strains. These might arise from a range of causes: inhomogeneous growth, plastic deformation, swelling or shrinkage driven by solvent absorption. Our analysis gives rigorous bounds on the convergence of the three dimensional equations of elasticity to the low-dimensional des...

For a soil to be granulometrically stable, it must present low plasticity and granulometric composition that conforms with the limits regulated by standards. This article presents study of clay fraction activity three laterites from Triângulo Mineiro region, aiming use them in stabilized base. The experimental phase contained determination liquidity limit, plastic sand equivalent silica sesquio...

PET plastic bottles are a major contributor to in all big cities, this Research, we assess Eco-Bricks (a possible solution disposal) from an experimental point of view. This Research paper aims the feasibility using as Eco Bricks, in-wall module material. study suggests Eco-blocks that filled with single-use waste posed for disposal, liberty reoccupying filler material when advanced recycling c...

This article presents the results of a comparative experimental study on influence date palm fibers to replace polypropylene used as reinforcement in self-compacting concrete (SCC). Indeed, use makes it possible reduce plastic shrinkage concrete. Date have mechanical characteristics (tensile strength and elasticity modulus) largely sufficient fibers. The natural has several advantages, they are...
