. 图27 被爆底层柱质量变化 Fig. 27 Mass change of blasted bottom column 聚脲弹性体加钢丝网共同防护的作用机理与聚脲单独防护的机理不同:聚脲弹性模量较大,能够在一定程度上反弹高速侵彻破片,但其强度不够,会产生较大变形,对结构造成破坏,此时,钢丝网因其材料强度高,与聚脲体联合作用时,能够限制聚脲弹性体的侧向位移,形成较大的反力,共同消耗冲击能量......
weight balance (AB-224, Phoenix Instruments, USA) was used to quantify the specific wear rate, which is expressed as the mass loss (mg) per normal load (kN) per total reciprocating distance (m). An optical profilometer (Contour GT-K, Bruker, USA) was used to observe the 3D profile of the wear track and to corroborate the results obtained from the mass-loss measurements. 3 Results and discussion 3.1......
simulations were conducted to understand the heat and mass transfer phenomenon in both SLM and DED processes. To illustrate the solidification path of NiTi SMAs, the single scanning track model......
. Figure 15 Material fusion and cracks at the 316L/CuSn10 interface Therefore, the fusion zone in Figure 15 finally formed. Marangoni convection promotes mass transfer between the 316L region......
reinforced Al matrix composites (PR-AlMCs) have great potential to be applied as light mass materials because of their superior mechanical and physical properties such as high specific strength......
of reinforcing particles. In this respect, the use of metal matrix composites (MMCs) reinforced with nano/micro- sized particles of low mass, good resistance to corrosion and wear, and excellent......
, is component of velocity vector for atom k, is component of position vector for atom k, mk is atomic mass of atom k, and denotes the force imposing on atom k and it results from the pairwise interaction......
[47,48], ρ is the mass density of Ti- 6Al-2Zr-1Mo-1V titanium alloy (4530 kg/m3), cV is the heat capacity (580 J/K), T0 is the ambient temperature (298 K) when implementing SHPB test, and WP......
-dependent. As shown in Table 1, a mixture with mass ratio of 1:2:4 (water, cement and sand) was used, and to reduce the differences between samples, pure water was used in the mixture. The diameter of sand......
