Impact Behavior of High-Strength Engineered Cementitious Composite and Concrete Layered Slabs

High strength Engineered Cementitious Composite (HS-ECC) is a promising material to be used in protective structures. Due to its high manufacturing efforts and cost compared to conventional concrete, nonlinear finite element (FE) simulation is performed to study the influence of replacing HS-ECC layers with concrete under drop weight impact load. Both materials are simulated using the MAT_72R3 material model impeded in LS-DYNA and verified with experimental results. Several FE slab models were developed to compare the impact responses of different configurations. This study as a whole will provide a guideline for researchers to carry out a performance and cost optimization for protective structure elements.
