Blast and Explosive Modeling - available on the Kindle.

Despite studying a discipline that first used the Finite Element Method for engineering design, Civil Engineers are often less exposed to advanced numerical analysis methods than Mechanical Engineers. One reason for this is the fact that the scope of design-codes is far wider in Civil Engineering. However, recent trends, worldwide, have brought to the fore aspects of civil design that were hitherto restricted to exotic and esoteric applications in the practice of warfare, and are accordingly less comprehensively covered by design-codes. Materials technology, too, has advanced tremendously in recent years.

The book is written in easy-to-understand language, avoids jargon, includes a glossary of terms and references for further study. It presents

  • the options available to engineers to use the finite element method to simulate explosions
  • the data required to effectively model these phenomena
  • the theory necessary to construct finite element models
  • apply advanced analysis techniques using Radioss

Areas covered include

  • pressure-impulse diagrams
  • pressure-waves and shock-waves
  • strain-rate effects
  • what a Hugoniot represents, and how to derive it
  • equations of state (including the JWL and Mie Gruneison EOS')
  • how to obtain the CJ (Chapman Jouguet) pressure and velocity for an explosive
  • detonation points and detonation timing
  • multiple phase ALE (arbitrary lagrange euler) models
  • choice of mesh sizes and element types
  • damage and failure models
  • explicit and implicit methods
  • data for common explosives (such as TNT and RDX)
  • examples using TNT, examples using Radioss

Prior experience with the finite element method is not essential, but is recommended. If you're a beginner you should probably read the free book A Designer's Guide to the Finite Element Method first.

Several chapters in the book are software-independent - the explanations apply to all commercially available finite element applications (including Abaqus, AutoDyn and LS-Dyna). The worked example uses Radioss. The book comes with a workbook that presents 4 sample problems complete with video-illustrations on the use of HyperMesh, HyperView and Radioss to setup and solve each example.
