“…The maximum forces obtained from simulations are 9310 N and 9620 N, respectively, and are higher than TF and AF. Assuming that the force impulse has a nonlinear behavior (Hockauf et al 2007, Rusinek et al 2008, Bektaş and Ağır 2013, Minak and Ghelli 2008, it is possible to use a shape function as bilinear, polynomial, exponential, among others. However, it is observed as described in the previous papers that a parabolic shape allows to mimic experimental result observations.…”

The paper is reporting some comparisons between experimental and numerical results in terms of failure mode, failure time and ballistic properties of mild steel sheet. Several projectile shapes have been considered to take into account the stress triaxiality effect on the failure mode during impact, penetration and perforation. The initial and residual velocities as well as the failure time have been measured during the tests to estimate more physical quantities. It has to be noticed that the failure time was defined using a High Speed Camera (HSC). Thanks to it, the impact forces (average and maximum level), were analyzed using numerical simulations together with an analytical description coupled to experimental observations. The key point of the model is the consideration of a shape function to define the pulse loading during perforation.

“…Factors influencing fabric response to, and therefore damage from impact, include (but are not limited to) shape, size, mass and material of the impactor; velocity and angle of the impact; fabric variables (fibre type(s) and properties, structure, compressibility, thickness, number of layers); and the interaction between the fabric and the impacting object, e.g. [22][23][24][25][26][27]. Clearly, different fabrics and fabric combinations respond to impact in different ways.…”
