Axial Compression analysis of a composite concrete steel column using an “X” shape steel section
Abstract In this tutorial, the simulation of axial compression test of a composite concrete column using X X-shaped steel section is performed. The Concrete Damaged Plasticity model is selected to consider the tension and compression behavior of the concrete column. The model is a continuum, plasticity-based, damage model for concrete. It assumes that the two […]
Using hysteresis energy model to perform the low cyclic fatigue damage
Introduction Low-cycle fatigue (LCF) is a type of fatigue failure that occurs in materials subjected to relatively high stress levels and a low number of cycles, typically less than 10⁴–10⁵ cycles. This phenomenon is common in components exposed to cyclic plastic deformation, such as those in aerospace, nuclear, and power generation industries. To model and […]

Analysis of close-range blast loading based on the CEL method over a concrete composite concrete slab
In recent years, there has been a rise in bombing terrorist attacks and accidental explosions worldwide. Recently, a new type of building Concrete slab-steel beam, has been proposed. The Coupled Eulerian-Lagrangian (CEL) method is a numerical approach that combines the Eulerian and Lagrangian finite element methods to address fluid-structure problems. By leveraging the strengths of […]
Analysis of a composite panel(CFRP-Ceramic-GFPP) under air blast load
Introduction: In modern engineering, multi-layer composite panels are widely used in defense, aerospace, and infrastructure due to their high strength-to-weight ratio, damage tolerance, and energy absorption capabilities. With increasing threats from blast and impact loading, it’s crucial to assess the performance of these panels under extreme dynamic conditions, such as an air blast explosion. This […]
Analysis and simulation of Exposed Column Base Plate Connections in Moment Frames under dynamic load
Introduction to Exposed Column Base Plate Connections in Moment Frames In structural engineering, moment frames are used to resist lateral loads (such as wind or seismic forces)through rigid frame action, which depends on the flexural stiffness of beam-to-column and column-to-base connections. A crucial component of this system is the exposed column base plate connection, especially […]
Earthquake and seismic analysis of geosynthetic-reinforced soil
Geosynthetic-reinforced soil (GRS) structures perform well during strong earthquakes due to their flexibility and integrity. This is evident from the 1994 Mw 6.8 Northridge earthquake, with recorded peak ground acceleration (PGA) values greater than 0.60 g. The variables associated with seismic ground motions, soil properties, and reinforcement parameters are full of uncertainties and pose threats […]
Analysis and simulation of high-velocity impact on a Composite panel(CFRP-Aluminum foam-Aluminum honeycomb-CFRP)
This study presents a comprehensive finite element simulation of a high-velocity impact on a hybrid composite sandwich panel consisting of Carbon Fiber Reinforced Polymer (CFRP) face sheets, an aluminum foam core, and an aluminum honeycomb mid-layer. The structural configuration aims to maximize energy absorption and minimize damage propagation under extreme dynamic loads. A spherical projectile […]
Bending test analysis of an RC beam with sustainable aluminum boxes filled with UHPC
Abstract This paper presents a numerical analysis of the shear improvement of defected reinforced concrete (RC) beams using sustainable aluminum boxes filled with high performance concrete. Introduction Reinforced concrete (RC) beams are fundamental structural elements in buildings and infrastructures, but they are susceptible to shear failure, especially when compromised by defects such as cracks, voids, […]
Finite element analysis on the air blast resistance of stiffened cylindrical tubular aluminum panel
Abstract Aluminum sandwich structures are widely used in modern engineering due to their lightweight, high stiffness, and energy absorption capabilities. These structures typically consist of two strong outer face sheets and a lightweight core (e.g., honeycomb, foam, or lattice). When subjected to air blast loads, such as those from explosions, these structures can help absorb […]
