Shock Parameter Measurement of Sub-Micrometer Aluminum Driven by Laser Using Frequency Domain Interferometer
TAO Tianjiong, WENG Jidong, WANG Xiang, LIU Shenggang, MA Heli, LI Chengjun, JIA Xing, CHEN Long, WU Jian, TANG Longhuang, CHEN Yongchao
2025, 39(4): 040101. doi: 10.11858/gywlxb.20240967
Abstract:

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 ablation. This process generated shock wave propagat...

Improvement of Lattice Parameter Accuracy in Single Crystal XRD Based on a Laser-Induced X-Ray Source
LIU Jin, WANG Qiannan, LI Jiangtao
2025, 39(4): 043401. doi: 10.11858/gywlxb.20240946
Abstract:

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 using the interaction points for the pseudo-Kossel p...

Dynamic Response of Matter
Dynamic Response Experiment of Prefabricated Wall Panels for a Whole-Indoor Substation under Blast Loading
LI Lin, LIU Yong, WEI Zhenzhong, MA Xiaomin, LEI Jianyin, LI Shiqiang
2025, 39(4): 044101. doi: 10.11858/gywlxb.20240873
Abstract:

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 investigated through experimental studies. The effects of o...

Numerical Study on Response of AZ31B Magnesium Alloy Subjected to High-Velocity Projectile Perforation
ZHOU Tao, LIU Yijun, WANG Zihao, YANG Kaihua
2025, 39(4): 044201. doi: 10.11858/gywlxb.20240868
Abstract:

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 AZ31B magnesium alloy subject to high-velocity imp...

Indentation Behavior of CoCrFeNiMn High-Entropy Alloys under Dynamic Loads
WU Kunkun, LIU Cong, SU Buyun, QIU Ji, SHU Xuefeng, KANG Zhengdong
2025, 39(4): 044202. doi: 10.11858/gywlxb.20251002
HTML PDF (10)
Abstract:

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 research object, compression, shear and micro-indentati...

Effect of Charge Defects on the Fast Cook-off Response Characteristics of Cast PBX Explosive Charge
LIANG Mingyang, ZHI Xiaoqi, YU Yongli, XIAO You
2025, 39(4): 045101. doi: 10.11858/gywlxb.20240893
Abstract:

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 that the response time of type Ⅱ cook-off bomb (128 s...
