Abaqus has always been a software of choice for modeling welding in various industries. This eSeminar will highlight the capabilities of the Abaqus Welding Interface (AWI), including some recent enhancements that make realistic simulation of the welding process possible in Abaqus.
The Abaqus Welding Interface (AWI) places an emphasis on the ease of weld model preparation and setup while supporting options and features that allow realistic predictions of quantities of interest such as distortion and residual stresses. A flux-based energy input option using the Goldak double ellipsoid model is now available for use with the AWI.
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.
Weld sequence optimization with ABAQUS welding interface Mahyar Asadi will present on the following at the SIMULIA technology day in Toronto OCT 18, 2017 Welding engineering is among one of the complex fields that has historically relied on the past experience of welding engineers. Abaqus Welding Interface. I want to simulate a 3D welding in Abaqus 6.14.1 and I'm not good enough in coding to work with Subroutines. I need a new version of this Plug in. For more information. I am using the ABAQUS Welding Interface. When I run the analysis, as the weld is deposited, the elements heat up to prescribed 1500degC, however close to the heat application, some elements go down to -140 degC. Over the entire analysis, the -140 degC increases and at the end of the analysis reaches 21degC. The Abaqus Welding Interface (AWI) described in this Capability Brief provides a capability to significantly improve two-dimensional welding simulations by automating most of the time consuming tasks associated with building a weld model.
Another significant enhancement takes advantage of the new, strain-free element activation technique developed by SIMULIA R&D that has applicability in many important areas, including welding. This new technique improves pre-processing and analysis performance significantly for models of processes involving material deposition such as welding and additive manufacturing. As a result, strain-free element activation is no longer a step-dependent feature.

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.
