Computational mesomechanics of particle-reinforced composites
Numerical models of deformation, damage and fracture in particle-reinforced composite materials, based on the method of multiphase ®nite elements (MPFE) and element elimination technique (EET), are presented in this paper. The applicability of these techniques for dierent materials and dierent levels of simulation was studied. The simulation of damage and crack growth was conducted for severa...
متن کاملEffects of particle size and weight percentage of heavy metal elements on photon shielding efficiency of reinforced polymer composites
Background: Polymer composites when reinforced with heavy metals in the form of micro/nano particles are efficient gamma- and X-ray shielding materials providing such advantageous features as cost-effectiveness, light-weight factor, flexibility, non-toxicity, conformability over conventional shields. Materials and Methods: In this paper the influence of weight percentages and particle sizes of ...
متن کاملCreep Behavior of Basalt and Glass Fiber Reinforced Epoxy Composites
The creep behavior of basalt fiber reinforced epoxy (BFRE) and glass fiber reinforced epoxy (GFRE) composites was studied through tensile testing at high temperature. To study the effect of reinforcing epoxy, the micro glass powder (MGP) was added at various volume percentage into the epoxy resin in BFRE composites. The initial strain for all the specimens were evaluated and compared with each ...
متن کاملFrequency-dependent electrical mixing law behavior in spherical particle composites
The electrical properties of cement-based composites with mono-size conductive (steel) or insulating (glass) spherical inclusions were investigated by combined 2-point impedance spectroscopy and 4-point dc resistance measurements. The matrix was ordinary Portland cement (w/c = 0.4; cured for 7 days). Particle loading was varied over an extended range to as high as 42% volume fraction. The steel...
متن کاملFlexural Behavior of Cementitious Composites Reinforced by Synthetic Fibers
The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...
