The Abaqus Welding Interface Plug-In (AWI) enables an easy, efficient, model-tree based approach to the setup all aspects of 2D and 3D welding models from within Abaqus/CAE, such as weld beads, weld passes, film loads, and radiation loads etc. ABAQUS allows direct user specification of the stiffness recovery factors. The experimental observation in most quasi-brittle materials, including concrete, is that the compressive stiffness is recovered upon crack closure as the load changes from tension to compression.

Abaqus Welding Interface (NSRP M&S 2)
Enables up-front realistic simulation of welded structures
Overview
Traditional consumable welding is a very common manufacturing method. But these common welding methods are also associated with a few expensive and sometimes undesirable processes such as flame straightening, weld testing, or trial and error with fixturing and path sequencing. All of these processes require time and materials, which ultimately results in added cost.
As part of the National Shipbuilding Research (NSRP) M&S 2 Project, Dassault Systèmes SIMULIA has developed a virtual welding application, called Abaqus Welding Interface (AWI), which provides the ability to virtually model the welding process and predict weld distortion and residual stresses. The result is reduced need for time-consumingphysical tests and manual corrections because SIMULIA tools predict if a given welding process/sequence will work.

Features & Benefits
- Automate time consuming tasks associated with building a weld model.
- Set up custom weld pass sequence or let plug-in automatically define.
- Easily create all the required analysis steps with appropriate data, the energy transport boundary conditions for each step, and the sets for sensor output requests (where applicable and available).
- Build the entire thermal model followed by the automatic generation of the corresponding mechanical model for thermal stress analysis.
- Modify and optimize the process before any actual material is welded.

Abstract:
The propagation behavior of crack with different initiation position is affected by the constraint effect differences in dissimilar weld joints mechanical heterogeneity. The ductile fracture model of interface crack in dissimilar weld joints was built by adopting extended finite element method; the propagation characteristic of interface crack was summarized. The results indicate that the strength mismatch of materials at sides of interface will increase trend of crack advancing into the relative soft material which has lower yield strength and lower hardening exponent.
