Overview of Elastic Orthotropic Fiber Reinforced Polymer Modular Damage Model for Library of Advanced Materials for Engineering (LAMÉ)

This memo includes the documentation sections for the Library of Advanced Materials for Engineering (LAMÉ) manual for a fiber reinforced polymer composite damage model (Elastic_Orthotropic_FRP_Modular_Damage) in advance of the next Sierra/SM and LAMÉ release consistent with the transition of the model from development to a production capability. This new model capability provides both a set of physically based orthotropic damage criteria as well as orthotropic material softening for woven fiber reinforced polymer composite materials. The documentation sections include short sections on theory, implementation, verification, and user guidance to prescribe the model in a Sierra/SM input file.

Overview of Geant4 Physics

Geant4 is a powerful toolkit for simulating particle interactions across a wide energy range (0 to ~TeV). It offers comprehensive physics processes for various particle types, allowing users to define custom processes using the G4VProcess interface. Major categories include electromagnetic, hadronic, decay, parameterized processes, and transportation. A critical feature is the PhysicsList, which specifies particles and processes for simulations. Users can choose between G4VUserPhysicsList for simpler environments or G4VModularPhysicsList for more complex scenarios, leveraging pre-defined or custom G4VPhysicsConstructors. Additionally, Geant4 provides reference physics lists and the G4PhysicsListFactory for well-established applications, facilitating simulation development in diverse domains.
