Abstract: Refractory high-entropy alloys (RHEAs) have attracted considerable attention due to their outstanding mechanical properties. However, the influence of their microstructural behavior on macroscopic mechanical performance remains poorly understood. With the increase of study on material micromechanica...
Abstract: A new type of irregular lattice structure base floor was proposed, and its blast resistance was characterized and optimized. The parametric modeling program for the lattice structure base floor was developed, the blast responses of the base floor were analyzed based on the finite element method, the...
Abstract: To find a reliable and universal plastic deformation mode of circular plates under impact loading, based on the energy method, a plastic deformation calculation model for circular plates under impact loading was established, with different deformation modes and material strain rate effects considere...
Abstract: As an essential construction material, the tempered glass has important research value and engineering application background for study on the failure law and protective performance under accidental strong dynamic loads such as explosion, earthquake, collision and typhoon. Experimental investigation...
Abstract: The effects of stand-off distance on explosive welding quality between titanium (TP 270C) and stainless steel (SUS 821L1) composite plates, were investigated. The 3D numerical simulations were conducted with the ANSYS/LS-DYNA software by 2 algorithms (the ALE method and the SPH-FEM coupling method) ...
Abstract: Steel fiber-reinforced concrete (SFRC) is the most utilized structural material for protective engineering. It is frequently subjected to complex stress states with high strain rates under strong dynamic loads, such as explosions and penetrations. Most current studies on the dynamic mechanical prope...
Abstract: To improve the crashworthiness of automotive collision energy absorption boxes under oblique impact loads, a new-type origami tube with a polygonal rotary splicing origami pattern was designed based on conventional square tubes. The drop hammer impact experiment and numerical simulation analysis wer...
Abstract: The key problems of the effective acquisition of low-impedance transmitted signals and the stress equilibrium in the Hopkinson bar loading tests on low-impedance specimens with high strain rates, were investigated. Based on the previous research fundaments, low-impedance elastic transmitted bars wer...
Abstract: To obtain the inclusion characteristics of carbon fiber resin matrix composite casing in service environment, 2 high-speed impact ballistic tests were conducted before and after hygrothermal treatment, and the corresponding simulation model for the casing hygroscopicity partition hygrothermal test s...
Abstract: The heat generated by flexible electronic devices during operation leads to deformation of the components, which is highly likely to affect their functionality. A finite element analysis model for the thermal impulse responses of the flexible electronic device element arrays were established, and th...
