Week 01 - Basics of Crashworthiness Physics, FEA Concepts and CAE Process
- In the first module you will learn about different types of analysis, the difference between implicit and explicit analysis, different non-linearities and, along with this, you will also bust the myth that ‘strong structure equates safe structure" by teaching you about:
- Meaning of crash safety for a vehicle.
- The Law of conservation of energy is applied to a car crash.
- Basic concepts of FEA, such as linear-nonlinear, static-dynamic, implicit-explicit analysis, their differences, and the guidelines on how to choose a method for a given FEA problem are explained.
Week 02 - Introduction to HyperMesh
- HyperMesh is one of the most popular Finite Element Preprocessor used to generate meshes
- of complex models. In this module, you will learn the GUI of HyperMesh, various elements available in FEA like 1D, 2D, and 3D elements, how to choose the element depending on the geometry by covering topics such as:
- Overview of Pre-Processors and their importance in FEA Processes
- Primary introduction to GUI of HyperMesh, toolbars, and basic operations
Week 03 - Geometry Editing in HyperMesh
- Learning to mesh geometries is an important step in performing FEA. Therefore, we will extensively cover the topic by which the students can understand, geometry clean up, tools available for geometry cleanups,
- Using an edited geometry to generate a mid-surface and an appropriate 2D mesh with regards to mesh flow, trias, and mesh size, by various methods.
- Using the geometry tools to clean up the distorted geometry.
Week 04 - Meshing – 1D, 2D & 3D and Mesh Quality Check
- In this section, you will learn about 1D, 2D, and 3D meshing, what mesh quality is and how to improve it, before exporting the meshed model to the specific solver.
- Using an edited geometry to generate a mid-surface and an appropriate 2D mesh with regards to mesh flow, trias, and mesh size, by various methods
- Using the geometry to create a 3D mesh using various methods.
- Meaning of mesh quality and ways to control and improve it
- Types of 1D elements, their specifications, and creation
- Exporting a meshed model from HyperMesh in the specified solver format
Week 05 - Introduction to Radioss
- In this section, you will learn what an explicit solver is, what an engine file and a starter file are, and their significance, as well as what an out file is and how to read this out file.
- Overview of Radioss: An Explicit FEA Solver for Crashworthiness
- Essential Radioss input files, their significance, and format
- An overview of output files and their significance
Week 06 - Element Properties and Materials
- In this section, you will learn about the various element formulations available for different types of elements in the Radioss and their applications, how to assign thickness to the component, and also various parameters available in the property card and their significance.
Similarly, you will also learn about the various material cards available in Radioss and their use cases along with their failure criteria.- Application of thickness and dimensional properties, integration points for 1D, 2D, and 3D elements
- Study and application of concepts such as material intrinsic properties, failure criteria, non-linearity, plasticity, and hyper-elasticity into a material model.
week 07 - HyperCrash, HyperView and HyperGraph
- In this section, you will learn about a new application that was developed by Altair exclusively to set up crash simulations, and along with this, you will be learning the GUI of Hypercrash. You will also be introduced to Hyperview and HyperGraph, where you will learn how to post-process the simulation results.
- An Introduction to HyperCrash, a specialized preprocessor for Radioss
- Introduction to HyperView and HyperGraph as post-processing tools in the FEA process
Week 08 - Interface (Contact) Modelling
- Interface modeling will be a complex topic that you can find in any solver. Here you will learn what contact is and how it works, what the different parameters you need to look into while defining a contact in a model are, and what the different types of contacts are and their use cases.
- Concepts of an interface between given components, penalty formulation method, contact stiffness, gap, penetration, interference, and tied interfaces
- Creation of various types of interfaces and removing any errors or interferences
Week 09 - Boundary Conditions Setup
- In this section, you will learn how to set up a proper boundary condition for any given simulation, what the different types of loading conditions are, and the different types of joints available in Radioss
- Setup of static and dynamic loading conditions such as velocity, acceleration, a constraint on degree of freedom, rigid walls, spot welds, and seam welds.
Week 10 - Simulation Control
- In this section, you will learn about the concept of the time step and how it can be optimized to increase the speed of the simulation, and also the concept of mass scaling. You will also understand the various control cards available in Radioss and their use cases.
- Control of simulation in terms of the time step, accuracy, run time, types of outputs
Week 11 - Checks and Debugs
- In this section, you will learn the various checks you should do before running the simulation and also how to debug a simulation along with its approach.
- Using diagnostic methods, check for and debug any errors in the model.
Week 12 - Airbag and its Modelling in FEA
- In this section, you will exclusively learn about the physics of an airbag in crash scenarios and how to model them in Radioss. You will be learning about two types of airbags (with vent and without vent).
- The concept of an airbag in FEA, its modeling methods and challenges with an example
Week 13 - Occupant Injury Criteria
- In this section, you will learn how the injury criteria are calculated in the actual crash test environment and how they affect the rating of the vehicle. You will also learn about the dummy standards that are used in crash testing.
