## 1 Introduction
For UHMWPE laminate, [PERSON] [21] studied the dynamic mechanical properties of UHMWPE fiber-reinforced composites with three different laminated angles (0\({}^{\circ}\)/90\({}^{\circ}\), 0\({}^{\circ}\)/90\({}^{\circ}\)/45\({}^{\circ}\)/\(-45^{\circ}\), 0\({}^{\circ}\)/90\({}^{\circ}\)/30\({}^{\circ}\)/\(-60^{\circ}\)/60\({}^{\circ}\)/\(-30^{\circ}\)) at higher strain rates under out-of-plane compression. The energy absorption capabilities were sensitive to the laminated angle of composites under medium-velocity impact. In addition, delamination and compaction in the thickness direction constituted the main dynamic failure mechanisms. [PERSON] [22] investigated both shear thickening fluid (STF)-treated and neat gold shield UHMWPE composites specimens subjected to high-strain-rate impact using Split Hopkinson pressure bar (SHPB) experiments. He studied the properties of the neat specimens under strain rates from 3120 to 13,100 s\({}^{-1}\) and the STF-treated specimens under strain rates from 5000 to 15,600 s\({}^{-1}\). The results

Moreover, the STF-treated gold shield specimens exhibited higher values of specimen peak stress, peak strain, specimen strain rate, and impact toughness as compared to the neat untreated specimens. In terms of simulations, there were some studies on the quasi-static compression [23], interlaminar shear [24; 25], and ballistic impact responses of UHMWPE laminate [14; 23]. [PERSON] [23] developed finite element (FE) models to verify mechanical test results under out-of-plane compression and got good agreement. [PERSON] [24] developed FE models and applied a surface-based traction-separation contact condition to simulate the nonlinear and unloading material behavior measured by digital image correlation (DIC). [PERSON] [14] developed an FE model for simulating a panel with AD (areal density) = 15 kg/m\({}^{2}\) impacted by a 6-mm-diameter aluminum sphere at a velocity of 3532 m/s. The results showed good agreement on the height and width of the ejecting debris cloud on the back face when compared with the ballistic experiment. Then, validation simulations of seven impact situations for an impact velocity range of 2052 m/s to 6591 m/s also showed good applicability and realistic perforation predictions in terms of the impact velocity-residual velocity relationship. [PERSON] [23] applied a new sub-laminate discretization approach to more accurately capture out-of-plane failure. The model was extensively validated using experimental ballistic data for a wide range of UHMWPE target thicknesses up to 102 mm against 12.7-mm and 20-mm caliber fragment simulating projectiles (FSPs) with impact velocities between 400 m/s and 2000 m/s. Very good overall agreement with experimental results was seen for depth of penetration, ballistic limit, and residual velocity, while the penetration mechanisms and target bulge behavior were accurately predicted. In terms of studies looking at the matrix individually, [PERSON] [26] built a cell unit containing a fiber model, matrix model, and cohesive elements between them. [PERSON] [27] modeled polyurethane matrix material into a strip, which, in the example, took 20% of the space in volume and was placed side by side with the fiber \"bundle\". However, the simulation of high-strain-rate compression of UHMWPE laminate is less studied than other kinds of fiber laminate [17; 28]. In terms of ballistic protection, there were some studies looking at smart materials and other fibers used. Smart materials like shear thickening fluid (STF) are used to enhance impact resistance. This smart fluid increases its viscosity under applied loadings and exhibits a solid-like state for a split second since the loading reaches upper levels [29].
