A Coupled Eulerian–Lagrangian (CEL) analysis of an underwater explosion near a pipeline is a numerical simulation approach widely used in nonlinear dynamics and hydrodynamics to model how shock waves and bubble effects from an explosion interact with nearby structures Modeling underwater explosions (UNDEX) is challenging because the event involves extreme ...

Super-austenitic stainless steels (SASS), distinguished by their high alloy content and superior corrosion resistance, have emerged as promising materials for blast-resilient structures operating in harsh marine environments. When configured as sandwich panels with metallic face sheets and lightweight cores, they offer a favorable combination of strength, ductility, and energy absorption. ...

Introduction to Underwater and Underground Explosion Phenomena in Abaqus Abaqus is a robust finite element analysis (FEA) software that simulates complex phenomena, including underwater and underground explosions. These simulations are crucial for defense applications, mining engineering, offshore structures, and protective design Underwater Explosions in Abaqus Rapid expansion of gas bubbles ...

In Abaqus, CEL (Coupled Eulerian-Lagrangian) and Eulerian analysis are advanced techniques used to model complex problems involving large deformations, fluid-structure interactions, and multiphase flows. These methods are particularly useful when traditional Lagrangian approaches struggle to handle severe mesh distortions or when fluid behavior dominates the problem Eulerian Analysis Eulerian analysis is a framework where ...

Numerical simulation of concrete-filled double skin steel tubular (CFDST) structure subjected to underwater explosion loading in Abaqus has been don in this example. The concrete column is modeled as a three-dimensional solid part. The inner and outer steel tubes are modeled as shell parts. The air, water, and TNT are ...

In this tutorial, the Simulation under water explosion shock over a cylindrical aluminum shell in interaction with soil in Abaqus has been studied. The water is modeled as a three-dimensional solid part with acoustic behaviour. The aluminum part is modeled as a three-dimensional shell part, and the soil as a ...

In this tutorial, the  simulation of Damage prediction of concrete gravity dams subjected to underwater explosion shock loading has been done. The concrete dam is modeled as a three-dimensional solid part. The TNT, water, and air are modeled as eulerian part. The rock foundation is modeled as a three-dimensional solid ...

In this course, we explained the Coupled Eulerian-Lagrangian, Smooth Particle Hydrodynamic, Acoustic, and CONWEP blast procedure in detail during twenty-three separate tutorials, which you can see their title below. We provide this course because some people use our tutorials to create courses on Udemy, but if you ask them questions ...
