Laser-induced microparticle impact testing (LIPIT) provides an effective experimental method for revealing the ultrahigh strain-rate dynamic response of materials by launching a single through laser-induced film expansion to target material. Understanding coupling effects laser ablation and responses both films microparticles during launch process in LIPIT is essential achieving higher velocity microparticle. In this study, influences elastomer thickness diameter on are investigated numerical simulations. The results show that plasma pressure experiences sudden increase system with thin or without due inertial effect reflection shock waves at microparticle–film interface. As increases, onset time delays amplitude peak decreases. When exceeds about 10 μm, influence negligible. Additionally, decreases increasing thickness. film, leads greater pressure, resulting velocity. However, when 9.2 begins decrease diameter. This study discloses insights into design optimization system.
