wave of the target produces tensile waves, which interacts with compressive waves possibly leading to spalling of the concrete [2]. Incorporating randomly discrete short fibers in concrete yields significant improvements in engineering properties, such as tensile and flexural capacities, ductility, resistance to fatigue, and impact loading [3]. In the early 2000s, a new kind of fiber-reinforced cementitious composite, commonly known as Engineered Cementitious Composite (ECC), had emerged. ECC exhibits superior tensile characteristics compared to that of conventional fiber-reinforced concrete (FRC) with strain capacity of up to 8% [4]. Owing to its superior mechanical performance, unique micro-cracking capability, energy absorption capacity, and impact resistance, ECC has become a strong contender for the construction of protective structures [5]. Cement, supplementary cementitious materials, micro-sand (typically less than 200 microns), water, and short fibers are the main constituents of ECC. Polyvinyl alcohol (PVA), polypropylene (PP), polyethylene (PE), rubber, and steel (SE) fibers have been utilized in the production of ECC. Recently, the authors have pioneered the use of short shape memory alloy (SMA) fibers in ECC production [6]. SMAs are a class of metallic alloys that \"remember\" their original shape, with unique ability to undergo large inelastic deformation and regain its un-deformed shape when subjected to stimuli, such as radiation, thermo-mechanical or magnetic variations, and electric heating. The unique behavior of ECC structural elements under impact loading has triggered significant research aiming at the development of design guidelines for ECC in protective structures. On the other hand, several experimental and numerical investigations have been conducted on the impact resistance of ECC elements. The most pertinent recent research work focused on the impact behavior of cement-based materials reinforced by mono-fibers [7; 8; 9] and/or hybrid-fibers with two different types of fibers or more [10; 11; 12]. Due to technical difficulties and the high cost of conducting large-scale missile impact tests, often small-scale drop weight impact testing has rather been adopted, despite the limitations associated with such a testing approach. For instance, [PERSON] et al. [13] investigated the impact resistance of hybrid-fiber ECC panels reinforced with 1.5% polyethylene (PE) and 0.5% steel fibers. Results showed that the ECC panels could perform as a protective material in various applications, such as improving shatter resistance with reduced scabbing and spalling associated with distributed micro-cracking. Furthermore, [PERSON] and [PERSON] [14] conducted a series of drop weight impact tests on hybrid-fiber-reinforced ECC panels and beams incorporating PVA and PE fibers. It was observed that the ductility of ECC specimens led to enhanced impact resistance through improving the load carrying capacity and energy dissipation capability of the tested structural elements. Similarly, [PERSON] et al. [10] concluded that a hybrid-fiber reinforced ECC incorporating a combination of 1.75% PVA and 0.58% steel fibers achieved superior performance and dissipated more energy when subjected to high-velocity projectiles than that of a control conventional concrete. Recently, [PERSON] et al. [6] experimentally investigated the impact resistance of SMA-ECC composites under drop weight impact. Up to six hundred blows were applied per specimen to cause a fracture, which reflects the time and efforts required to conduct such tests. Therefore, numerical simulation is a highly attractive alternative considering the costs and difficulties of experimental tests. For an accurate numerical prediction of the impact behavior of ECC structures, adequate material models, which can represent the dynamic behavior of ECC, are essential [2]. Various commercial codes have emerged modeling the dynamic behavior of concrete materials, such as ABAQUS, ANSYS, AUTODYN, and LS-DYNA.
