This tutorial simulates the low-energy impact of a rigid hammer on a three-layer wood-cement-concrete panel in Abaqus. The panel includes a wood-cement layer on top, normal-strength concrete in the middle, and another wood-cement layer at the bottom. The hammer is modeled as a rigid shell body, and only one-quarter of the model is used due to symmetry. Wood-cement composites provide a sustainable alternative to traditional materials by combining bio-sourced fibers with cement, making them suitable for permanent formwork and reducing environmental impact in construction. The Concrete Damaged Plasticity (CDP) model is applied to both the wood-cement and concrete layers to capture their inelastic behavior under tension and compression. A dynamic explicit step is chosen for the analysis. Perfect contact is assumed between the layers, while surface-to-surface contact is defined between the hammer and panel. Symmetry boundary conditions are applied to the panel, and an initial velocity is assigned to the hammer. A fine mesh ensures accurate results. After the simulation, results including stress, strain, damage, and deformation are available.
