For aluminum films with submicron thickness deposited on quartz substrates, femtosecond laser pulses (35 fs pulse width, 0.5 mJ energy, and a central wavelength of 800 nm) were focused on the surface to induce rapid thermal expansion through laser ab...

The lattice parameter, measured with sufficient accuracy, can be utilized to evaluate the quality of single crystals and to determine the equation of state for materials. We propose an iterative method for obtaining more precise lattice parameters us...

A novel prefabricated wall panel structure for substations was developed by integrating fiber cement board, aluminum honeycomb plate, and aluminum alloy plate. The dynamic response characteristics of the structure under explosive loads were investiga...

Magnesium alloys have been widely utilized in the automotive, aerospace, and electronics industries. In this paper, a dynamic constitutive model for metal was developed and integrated into a VUMAT user subroutine to precisely predict the behavior of ...

To address the challenge of evaluating the internal stress of materials or structures in service environments, a method combining finite element analysis and micro-indentation testing is proposed. Taking the CoCrFeNiMn high-entropy alloy as the resea...

To study the effect of explosive charge defects on fast cook-off response characteristics, fast cook-off tests were conducted on type Ⅰ cook-off bomb (with defect-free charges) and type Ⅱ cook-off bomb (with defective charges). The results showed tha...

In order to explore the influence of inorganic salts on the dissolution temperature of ammonium nitrate and the explosive performance of expanded ammonium nitrate explosives, the inorganic salts of 2%, 4% and 6% of NaCl, KCl, NaNO₃ and KNO₃ respectiv...

Explosion suppression technology plays a vital role in reducing the hazardous effect of gas explosion incidents. This study aimed to investigate the explosion suppression effect of two-phase composite inhibitor mixtures of hexafluoropropane and dry w...

To investigate the effects of different layers of carbon fiber reinforced plastic (CFRP) on the mechanical properties and energy evolution of axially compressed cylindrical coal samples, the finite difference method-discrete element method (FDM-DEM) ...
