TL;DR: In this paper, the authors investigated the cracks in a silica particle-filled epoxy resin composite system in air as a function of volume fraction of particles for volume fractions ranging from 0 to 0.52.
Abstract: The mechanical properties of a silica particle-filled epoxy resin composite system have been investigated in air as a function of volume fraction of particles for volume fractions ranging from 0 to 0.52. The Young's modulus and the compressive yield stress both increase as the volume fraction of silica particles is increased and various models of particle strengthening have been used to explain this behaviour. Slow crack growth in the various particulate composites has been studied using a fracture mechanics approach. The variation of crack velocity (V) with stress intensity factor (KI) has been measured for each of the compositions investigated. In each case, a unique relationship between V and KI has been found with KI increasing with volume fraction of particles at a given value of V. The failure mechanisms and the variation of other fracture mechanics parameters, for example, crack opening displacement and plastic zone size with increasing particle volume fraction have been discussed.

TL;DR: In this article, an investigation was carried out on MHD stagnation point flow of water based nanofluids (Cu and Al 2 O 3 ) in which the heat and mass transfer includes the effects of volume fraction of nanoparticles, radiation, viscous dissipation and chemical reaction.

TL;DR: In this article, a lattice Boltzmann (LB) method is developed to solve the solid-liquid phase change coupled with natural convection, in which two sets of evolution functions (density evolution function and temperature evolution function) are constructed to simulate fluid flow and heat transfer.

TL;DR: In this paper, the effects of Si content on the aging behavior and mechanical properties (formability) of alloys based on the AA6016 composition are described and the effect of Si within the alloy influences the solution heat treated (T4) strength and subsequent aging response of the 6xxx series alloys, again predominantly through its effect on the volume fraction of Mg2Si.
Abstract: The heat treatable 6xxx series (Al–Mg–Si–(Cu)) aluminium alloys are finding increasing use in automotive skin panel applications where relatively high formability and in-service strength for dent resistance are major requirements In Europe, the alloy of choice for such applications is currently the low Cu-containing alloy AA6016, which typically contains approximately 04 wt% Mg and 10 wt% Si, and which derives its strength from the precipitation hardening phase, Mg2Si The volume fraction of Mg2Si is, in turn, affected primarily through the level of Mg within the alloy, although the Si content is also important The level of Si within the alloy influences the solution heat treated (T4) strength and the subsequent aging response of the 6xxx series alloys, again predominantly through its effect on the volume fraction of Mg2Si In this paper, the effects of Si content on the aging behaviour and mechanical properties (formability) of alloys based on the AA6016 composition are described

TL;DR: In this paper, a kind of polymer composite was fabricated using polystyrene as the matrix and Si3N4 powder as filler employing the method of heat press molding, and the effect of the volume fraction of the filler, the particle size and the silane treatment of filler on the thermal conductivity of the composite was investigated.
