JH2 and JHB brittle damage package
JH2 and JHB JH2 (Johnson Holmquist II) and JHB (Johnson Holmquist Beissel) material models. These are specialized constitutive models used in computational mechanics (often in hydrocode simulations like ABAQUS, LS-DYNA, AUTODYN, CTH, etc.) for representing the response of brittle materials (e.g., ceramics, glass, rocks, concrete) under large strains, high strain rates, and high pressures. This […]
FSI and CFD Analysis Package
Introduction to Fluid-Structure Interaction (FSI) Fluid-Structure Interaction (FSI) refers to the mutual interaction between a fluid (liquid or gas) and a solid structure. In an FSI system, the motion or deformation of the structure affects the flow of the fluid, and conversely, the fluid’s pressure and forces affect the structural response. This bidirectional coupling makes […]
Earthquake and Seismic Analysis Package
Introduction to Earthquake and Seismic Analysis An earthquake is the sudden release of energy stored in the Earth’s lithosphere, causing seismic waves that shake the ground. These events are usually triggered by the movement of tectonic plates along faults, volcanic activity, or other stress accumulations in the Earth’s crust. Depending on their magnitude and depth, […]
DEM and SPH Analysis Package
Introduction to DEM and SPH Analysis The Discrete Element Method (DEM) and Smoothed Particle Hydrodynamics (SPH) are powerful numerical methods used to simulate and analyze systems involving discrete particles, fluid flows, and their interactions with solid structures. These methods have become essential tools in engineering, geomechanics, materials science, and Multiphysics research. This package includes 20 […]
Composite Analysis and Simulation Package
Introduction to Composite Material Analysis and Simulation Composite materials are engineered by combining two or more constituent materials with different physical and chemical properties to achieve superior performance compared to their individual components. Typically, composites consist of a matrix material (such as a polymer, metal, or ceramic) reinforced with fibers or particles (such as carbon, […]
High-velocity impact analysis of the composite sandwich panels with GFRP faces and an aluminum foam core
Composite sandwich panels are widely used in aerospace, automotive, marine, and protective structures due to their exceptional stiffness-to-weight ratio, energy absorption capability, and structural efficiency. A typical sandwich configuration consists of two high-strength face sheets bonded to a lightweight core, enabling the panel to carry bending loads efficiently while minimizing mass. Among various material combinations, […]
Analysis of the SSFRRC composite beam under air blast load
The increasing threat of accidental and intentional explosions in industrial facilities, military infrastructures, and critical civil structures has highlighted the necessity for construction materials with superior resistance to extreme dynamic loads. Conventional reinforced concrete, although widely used due to its strength and durability, exhibits brittle behavior and limited energy absorption capacity when subjected to high-intensity […]
Beam-Column Joint Analysis and Simulation Package
Introduction to Beam Column Joint Simulation and Analysis Beam column joints are critical regions in framed structures where beams and columns intersect, transferring loads and moments between the vertical and horizontal members. The structural performance of these joints significantly influences the overall stability, ductility, and energy dissipation capacity of a building, especially under lateral loads […]
Ceramic and Silicon Carbide Analysis Package in Abaqus
Introduction to Ceramic and Silicon Carbide Analysis Using the Finite Element Method (FEM) 1. Overview Ceramic materials, particularly Silicon Carbide (SiC), play a crucial role in advanced engineering applications where high strength, stiffness, wear resistance, and thermal stability are required. However, their brittle nature and complex failure mechanisms make experimental characterization difficult and expensive. Therefore, […]
Analysis of Rubberized Concrete Interlocking Masonry under Vertical Loading
Interlocking masonry systems have gained significant attention in modern construction due to their ease of assembly, reduced need for skilled labor, and improved structural performance under various loading conditions. Unlike conventional masonry, interlocking units rely on geometric interlock rather than mortar bonds, providing benefits such as rapid construction, enhanced alignment, and increased energy dissipation capacity.
