摘要

为评估叠合靶板在中速(100-250 m/s)弹丸冲击下的动态响应，进行了详细的实验和数值研究。采用单级气枪将半球形弹和钝形弹分别发射到两种不同的异堆叠构型(Al-St和St-Al)上。通过综合实验(高速3D-DIC)和数值(FE)评估，获得了靶板的瞬态和后冲击行为。详细研究了不同弹丸形状对不同堆垛构型的全场瞬态变形曲线的影响。此外，还仔细测量和分析了典型的射孔参数，如桥塞尺寸、形状和射孔孔径。采用综合误差度量方法对实验结果与仿真结果的相似性进行了量化，结果表明两者吻合良好。

Evaluation of hetro-stacked target plate response toward different nose shaped projectile impact

Detailed experimental and numerical investigations were carried out for evaluating the dynamic response of the stacked target plates toward moderate (100–250 m/s) velocity projectile impact. A single stage gas gun was utilized to launch the hemispherical and the blunt projectile toward two different hetro-stacked configurations (Al-St and St-Al). A comprehensive experimental (high speed 3D-DIC) and numerical (FE) evaluation was conducted to obtain the transient and post-impact behavior of the target plates. Influence of different projectile shapes on the full-field transient deformation profiles of different stacking configurations was studied in detail. Also, typical perforation parameters like plug size, shape, and perforation hole diameters were carefully measured and analyzed. A comprehensive error measure was utilized to quantify the similarity between the experimental and simulation results, a very good agreement was observed.

期刊介绍： The Journal of Strain Analysis for Engineering Design provides a forum for work relating to the measurement and analysis of strain that is appropriate to engineering design and practice. "Since launching in 1965, The Journal of Strain Analysis has been a collegiate effort, dedicated to providing exemplary service to our authors. We welcome contributions related to analytical, experimental, and numerical techniques for the analysis and/or measurement of stress and/or strain, or studies of relevant material properties and failure modes. Our international Editorial Board contains experts in all of these fields and is keen to encourage papers on novel techniques and innovative applications."
