The response of tissue to penetration by non-deforming but yawing projectile is nicely shown in the diagram presented by Fackler (1996) and reproduced here in Figure 11.3. These experiments are usually carried out in ballistic gelatin or similar tissue simulants.

The material involved in this study is ballistic gelatin (BG) which is considered in the literature as a good soft tissue simulant. Mathematical law needs to be implemented in the computation for the modeling of the mechanical behavior. Thus, similar to the study of Taddei et al. [25], the constitutive law of the ballistic gelatin proposed in this work is a combination of the Mie Gruneisen equation of state coupled with a constitutive law defining the deviatoric stress components of the stress tensor. Then, the following equations can be written as with Γ being the Gruneisen parameter linked to thermomechanical behavior. The pressure term ph is associated with the Hugoniot curve with the following Ck coefficient:
