    Frontiers Strain Rate Effect on Mechanical Properties of

    As a kind of metamaterial, the negative Poisson’s ratio foams, which expand (shrink) in the transverse direction when stretched (compressed) in the longitudinal direction, have many potential applications in fields such as aerospace and mechanical and biomedical engineering. In this paper, the out-of-plane crushing behaviors of four types of the orthogonal isotropic NPR convex-concave foams ...

    Study on the Mechanical Properties of Bionic Protection

    A novel protective structure, based on shrimp chela structure and the shape of odontodactylus scyllarus, has been shown to improve impact resistance and energy absorption. A finite element model of NiTi alloy with shape memory was constructed based on the basic principles of structural bionics. The protective structure utilizes NiTi alloy as the matrix, a material with many advantages ...

    Mechanical characteristics of oil palm fiber reinforced

    Jan 17, 2020 Fibers are increasingly in demand for a wide range of polymer composite materials. This study’s purpose was the development of oil palm fiber (OPF) mixed with the thermoplastic material acrylonitrile butadiene styrene (ABS) as a composite filament for fused deposition modeling (FDM). The mechanical properties of this composite filament were then analyzed. OPF is a fiber extracted from …

    preparation of cement in chemistry SeeKing

    ADVERTISEMENTS: Portland cement can be manufactured by intimately mixing together calcareous and argillaceous stones containing silica, alumina, and iron oxide etc. and burning it in large rotary kilns at a temperature of approximately 1400 C to 1500 C. At his temperature the materials partially fuse, forming clinker. This clinker is cooled and ground to fine power.
