As emerging advanced construction materials, strain hardening cementitious composites (SHCCs) have seen increasing field applications recently to take advantage of its unique tensile strain hardening behavior, yet existing uniaxial tensile tests are relatively complicated and sometime difficult to implement, particularly for quality control purpose in field applications. This paper presents a n...

In this work, a numerical model is developed for simulating the compression molding process of hybrid composite material, alternately laminated with continuous and discontinuous fiber-reinforced layers. Although various simulation models are already available plastic materials embedding each type reinforcements, they incapable simultaneously dealing continuity discontinuity. Here, thermomechani...

background the goal of the present study was the preparation and evaluation of griseofulvin topical gel as a drug dosage form with appropriate efficacy and stability. material and methods to select the best formulation, formulations with different concentration of carbomer and hpmc were evaluated for their appearance. then evaluated for physicochemical characteristics such as rheologic behavior...

This paper advances an analytical incremental contact model for the purely elastic or elastic-perfectly plastic Gaussian rough surfaces. The is modelled by accumulation of identical circular contacts with radius given total truncated area at varying heights divided patch number. area-load relationship derived analytically, showing approximate linearity fraction up to 10%. Good agreement found b...

A knowledge of the behavior of chondrocytes in culture is relevant for tissue engineering. Chondrocytes dedifferentiate to a fibroblast-like phenotype on plastic surfaces. Dedifferentiation is reversible if these cells are then cultured in suspension. In this report a description is given of how when chondrocyte aggregates formed in suspension are next seeded on plastic, most of them attach as ...

This paper aims to gain an understanding of the reliability of the existing separation criteria for orthogonal metal cutting. To focus on their physical inherence, a simple finite element model under plane-strain deformation was used to investigate the mechanics of cutting from the incipient stage. The workpiece materials studied were elastic–perfectly plastic and elastic–plastic with work hard...

Good slip resistant tread patterns of outer-sole of military boot are vital to minimize the risk or severity of slip in combat and physical training situations. A series of non-linear, three-dimensional finite element analyses of footwear and ground interaction based upon the Drucker-Prager elastic-perfectly plastic material model was investigated. This study was aimed at how plastic failure of...

A method for simulation of elastoplastic solids in multibody systems with nonsmooth and multidomain dynamics is developed. The solid is discretised into pseudoparticles using the meshfree moving least squares method for computing the strain tensor. The particle’s strain and stress tensor variables are mapped to a compliant deformation constraint. The discretised solid model thus fit a unified f...
