“…The rich information contained in the cavity dynamics imaged with high temporal and spatial resolutions in addition to particle trajectories can be used to calibrate materials models for high-rate deformations [40,41]. The elastic recoil has been observed previously for macroscale particle impact on viscoelastic gels [42].…”

“…High-velocity penetration trajectories in gel materials have also been described using a Poncelet model, often for high-velocity impact on gelatins, with reasonable success [35,40,51,52]. In this model, the expression for the force acting on the particle consists of only two terms, the inertial drag term and the resistance term, neglecting the viscous term contribution [53][54][55]:…”

Background: Impact experiments, routinely performed at the macroscale, have long been used to study mechanical properties of materials. Microscale high-velocity impact, relevant to applications such as ballistic drug delivery has remained largely unexplored at the level of a single impact event. Objective: In this work, we study the mechanical behavior of polymer gels subjected to high-velocity microparticle impact, with strain rates up to 10 7 s -1 , through direct visualization of the impact dynamics. Methods: In an all-optical laserinduced particle impact test, 10-24 μm diameter steel microparticles are accelerated through a laser ablation process to velocities ranging from 50 to 1000 m/s. Impact events are monitored using a high-speed multiframe camera with nanosecond time resolution. Results: We measure microparticle trajectories and extract both maximum and final penetration depths for a range of particle sizes, velocities, and gel concentrations. We propose a modified Clift-Gauvin model and demonstrate that it adequately describes both individual trajectories and penetration depths. The model parameters, namely, the apparent viscosity and impact resistance, are extracted for a range of polymer concentrations. Conclusions: Laser-induced microparticle impact test makes it possible to perform reproducible measurements of the single particle impact dynamics on gels and provides a quantitative basis for understanding these dynamics. We show that the modified Clift-Gauvin model, which accounts for the velocity dependence of the drag coefficient, offers a better agreement with the experimental data than the more commonly-used Poncelet model.

The tissue analog targets (TATs) are widely used in biodamage and weapon damage effectiveness evaluation research. Given the issues of commonly used TATs, such as the low plasticity of gelatin and the environmental pollution caused by the fabrication of soap, this paper innovatively proposes to use paraffin as the raw material for making TATs. Firstly, the paraffin target samples are prepared by melt casting process, and the quasi‐static mechanical properties, antibullet properties, and corresponding ballistic characteristics of paraffin targets are obtained by MTS quasi‐static test and 7.62 mm ballistic gun test, respectively. Then, LS‐DYNA is utilized to construct the finite‐element (FE) model of fragment penetration on a ballistic paraffin target. After validating the FE model with ballistic gun test data, we systematically simulate the ballistic penetration behavior of fragments with different materials, shapes, and geometries on ballistic paraffin targets, and reveal the relationship between the depth of penetration of the ballistic paraffin target and the impact velocity of various fragments. Based on the classic penetration resistance theory, a theoretical model for predicting the depth of penetration on ballistic paraffin targets has been established, and the quantitative expressions for the fragment shape and material parameters in the proposed model are given by considering both data of the ballistic gun test and the FE simulation. This work can provide novel ideas and methods for the development and upgrading of TATs.
