Explosion Simulation Abaqus Tutorial

Learn Abaqus Explosion Simulation with this comprehensive tutorial, designed for mechanical and civil engineering students and engineers looking to expand their finite element analysis skills. This course provides a practical understanding of simulating various explosion conditions across diverse applications.

What You'll Master:

This course is structured into four sections, building upon foundational concepts. We strongly recommend following the order for optimal learning.

• Section 1: Air-Blast Simulation

  • Utilize the CONWEP model for air-blast loading on solid and structural elements without fluid modeling.
  • Explore concrete damaged plasticity (CDP) and the Johnson-Holmquist model for modeling explosions in concrete structures.
  • Familiarize yourself with the Hasin and Johnson-Cook damage models through practical examples like car door explosions and composite beam simulations.
  • Important: This section lays the groundwork for all subsequent theories.

• Section 2: Smoothed Particle Hydrodynamics (SPH) Explosions

  • Discover the Smoothed Particle Hydrodynamics (SPH) method, a meshless technique for simulating complex phenomena.
  • Apply SPH to concrete beam and water-tank explosions.
  • Understand applications like bird-strike simulations on aircraft fuselages and jet engines.
  • Learn to model gunpowder explosions in bullet shells using bullet examples.

• Section 3: Coupled Eulerian-Lagrangian (CEL) Method

  • Combine Lagrangian and Eulerian mesh approaches for simulations involving extreme deformations.
  • Simulate various explosion conditions on structures like concrete beams, underground pipelines, and soil.
  • Explore advanced applications such as bird strike simulations on aeroplane wings.

• Section 4: Underwater Explosion (UNDEX) Analysis

  • Simulate underwater explosions, focusing on wave propagation and structural loading.
  • Understand the UNDEX charge method.
  • Apply ductile and shear damage models in Abaqus to analyze submarine and ship structures subjected to underwater explosions.
