Abaqus/Explicit: Advanced Topics

Lesson 1: 
Overview of Abaqus/Explicit  

• Understand what dynamic equilibrium equation, energy balance, explicit dynamic integration method, stress wave propagation mean, and learn how to define Abaqus/Explicit procedure, stable time increment, bulk viscosity damping, and monitor the job and diagnostic messages issued by Abaqus/Explicit during an analysis, visualize and filter outputs.

 Lesson 3: 
Contact Modeling 

• Learn about the basic features, advantages and disadvantages of the algorithms used in Abaqus/Explicit to model and solve contact problems, and explore the available options to conduct successful contact simulations for Keywords and Abaqus/CAE interfaces.

Lesson 4: 
Quasi-Static Analyses 

• Learn how to solve quasi-static loading problems economically by using Abaqus/Explicit while artificially increasing the load rates or speed of the simulation process, and understand how to keep the inertial forces insignificant and examine the energy content to reflect an acceptable solution. 

Lesson 5: 
Constraints and Connections  

• Understand the concept and utilization of constraints, which comprise rigid bodies, coupling constraints, shell-to-solid coupling, surface-based ties, and connections including connector elements, mesh-independent fasteners, and cohesive connections.

Lesson 6: 
Impact and Post-buckling Analyses

• Learn how to set-up an impact model in Abaqus/Explicit with initial model configuration, selection of suitable elements, material models, constraints, contact algorithms and output parameters, and investigate post-buckling problems with the correct analysis procedure type and geometric imperfections.

Lesson 7: 
Material Damage and Failure

• Explore the capabilities for modelling progressive damage and failure for ductile metals, fiber-reinforced materials and interface materials provided by Abaqus/Explicit, and learn about the tools such as for damage initiation, damage evolution and element removal.

Lesson 8: 
Importing and Transferring Results 

• Learn how to import and transfer results and associated states between Abaqus/Explicit and Abaqus/Standard solvers, and explore the tools and keywords used for these purposes with intuitive examples in Abaqus/CAE and Keywords Interfaces, respectively. 

Lesson 9: 
Managing Large Models 

• Understand what large model means, the requirements for simplifications and techniques for large model management, learn how to conduct parallel execution and CPU time reduction strategies, submodeling and restart analysis.

Lesson 10: 
Output Filtering 

• Learn about attenuation strategies for high-frequency solution noise by means of run-time filters in Abaqus/Explicit and postprocessing filters in Abaqus/Viewer, and exploring the available tools to prevent result aliasing.
