Modeling of temporary cavity in ballistic gelatin based on spherical cavity expansion model
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2023To investigate the expansion mechanism of the temporary cavity produced by high-speed penetrators into ballistic gelatin, a dynamic spherical-cavity-expansion model for gelatin targets was proposed with consideration of the outer boundary size. The theoretical solution of the cavity radial stress was obtained and the energy conversion and conservation

Experimental investigation on the characteristics of temporary cavity in BABT with 9 mm projectiles
Forensic Science International, 2021Temporary cavity, one physical phenomenon in BABT reflects the dynamic response of biological tissues and is used to evaluate the trauma. To clarify the characteristics of cavity evolution during 9 mm Luger penetration, we obtain the deformation profiles by using an experimental method with a high-speed camera and thereby visualize the cavity formation

Evaluation of the temporary cavity in ordnance gelatine
Forensic Science International, 2012Gelatine is a recognized tissue simulant in wound ballistic research. The deceleration of a bullet causes a temporary cavity which provokes radial fissures by stretching the gelatine. The evaluation of gelatine destruction was performed with very different methods yet, widely known are the wound profile by Fackler and the total crack length (TCL ...

Visualisation of the temporary cavity by computed tomography using contrast material
International Journal of Legal Medicine, 2011The temporary cavity of a missile produces radial tears in ordnance gelatine, which correlate to the energy transfer. Computed tomography is a useful and non-destructive method to examine gelatine blocks. However, the tears give only few radiocontrast by air filling, which decreases with the time past shooting.

Accuracy of Temporary Laser Welding of FPDs by Nd:YAG Laser in the Oral Cavity
Dental Materials Journal, 2006 The purpose of this study was to investigate the accuracy of temporary fixation with laser welding for fixed partial dentures (FPDs). Five kinds of experimental FPD with different welding/soldering gaps were fabricated (0, 20, 50 microm for welding; 300 microm for soldering). Then, FPDs were temporary-fixed by laser welding or with a self-curing resin.

Stress Wave in Gelatin from Temporary Cavity
Applied Mechanics and Materials, 2013To study the injury mechanism of stress wave from temporary cavity in gelatin, a stress wave propagation model is established. Based on experimental phenomena, gelatin around the trajectory is divided into fail region and elastic region. In the fail region, gelatin is considered to be incompressible and loop stress is zero.
