# Abaqus Theory Manual
|
|
|
|
## Summary
|
|
|
|
The Abaqus Theory Manual is a broad theory reference for Abaqus finite element analysis. It describes the mechanics, finite element formulations, solution procedures, element behavior, constitutive models, contact treatment, loading, constraints, and coupled-field procedures behind ABAQUS/Standard, ABAQUS/Explicit, and related Abaqus tools.
|
|
|
|
## Scope
|
|
|
|
The manual begins with notation, rotations, stress measures, equilibrium, and nonlinear finite element equations. It then organizes the Abaqus theory base into analysis procedures, element formulations, mechanical constitutive models, interface modeling, and loading or constraint definitions.
|
|
|
|
For this wiki, the source functions as an industrial finite element atlas. It links the textbook-level finite element concepts from [[Finite Element Procedures]] to implementation-facing choices such as Newton iteration, automatic incrementation, reduced integration, hybrid incompressible elements, material-point stress updates, and contact constraints.
|
|
|
|
## Extracted Threads
|
|
|
|
- [[Abaqus Analysis Procedures]] - nonlinear static, dynamic, modal, buckling, coupled-field, fracture, substructuring, and design-sensitivity procedure families.
|
|
- [[Abaqus Element Library]] - isoparametric interpolation, numerical integration, continuum, shell, beam, membrane, truss, rebar, hydrostatic fluid, and special-purpose elements.
|
|
- [[Reduced Integration and Hourglass Control]] - reduced quadrature, Barlow-point accuracy, zero-energy modes, and artificial stiffness controls.
|
|
- [[Hybrid Incompressible Elements]] - mixed displacement-pressure treatment for fully or nearly incompressible materials.
|
|
- [[Abaqus Constitutive Integration]] - integration-point stress updates, state variables, material Jacobians, and backward-Euler plasticity integration.
|
|
- [[Finite Element Contact Formulation]] - surface interaction and contact constraints for deformable and rigid bodies.
|
|
|
|
## Connections
|
|
|
|
This source expands [[ABAQUS]] from a validation software reference into a documented finite element theory system. It also gives implementation context for [[Nonlinear Finite Element Analysis]], [[Isoparametric Finite Elements]], [[Mixed Finite Element Formulations]], [[Direct Time Integration Methods]], and [[Finite Element Eigenproblem Solvers]].
|
|
|
|
[[Abaqus-Analysis-User-s-Guide-Volume-I|Abaqus Analysis User's Guide Volume I]] complements this source by showing how the theory-backed procedures and element choices are exposed through input files, spatial model definitions, execution commands, resource settings, and output files.
|
|
|
|
[[Abaqus-Analysis-User-s-Guide-Volume-II|Abaqus Analysis User's Guide Volume II]] complements this source by showing how analysis procedures and special techniques are selected, controlled, continued, coupled, reduced, adapted, optimized, and extended in production Abaqus workflows.
