ADVANCED ABAQUS SUBROUTINE COURSE

This course serves as an extensive guide to Abaqus subroutines, offering a powerful means to expand the software’s capabilities. It covers a wide array of subroutines, including:

Material Subroutines:

• UMAT and VUMAT: These are used to create complex material models that aren’t available in Abaqus by default.
• USDFLD and VUSDFLD: Allow the definition of material properties that vary based on different conditions.
• UHYPER Subroutine: Used to define strain energy for hyperelastic isotropic materials.
• UHARD and VUHARD Subroutines: Enable users to define custom hardening models.
• UMATHT Subroutine: Utilized for specifying a material’s thermal behavior.

Load Subroutines:

• VDLOAD and DLOAD: Allow the definition of complex loading conditions.
• DFLUX Subroutine: Used for thermal loading scenarios where heat flux depends on other variables.
• UAMP and VUAMP Subroutines: Define time-dependent loads and boundary conditions.

Boundary Condition Subroutines:

• DISP and VDISP Subroutines: Used to specify complex boundary conditions.

Mesh Subroutines:

• UMESHMOTION Subroutine: Facilitates mesh motion for adaptive meshing techniques.

Other Subroutines:

• UEL and VUEL Subroutines: Applied with the Abaqus Explicit solver to define custom element behavior for complex materials and elements.
• VFRICTION and VFRIC Subroutines: Used to simulate friction in complex situations.
• UVARM and VUVARM Subroutines: Define user-specific output variables at material calculation points.
• UEXPAN and VUEXPAN Subroutines: Specify incremental thermal strains.
• HETVAL Subroutine: Used for defining heat flux due to internal heat generation within a material.

The course also includes workshops that demonstrate how to apply these subroutines to solve specific engineering problems. Overall, it is an invaluable resource for anyone looking to master Abaqus subroutines to create custom material models, loads, boundary conditions, and more.
