Abaqus Welding Interface Cracked

Welding in Abaqus. Hello I need to simulate welding in Abaqus. I have a bucket that transfer heat to a plate, I'm using cavity radiation but in a heat transfer step I. Superior Drummer Sdx Keygen. Using ABAQUS Cohesive Elements to Model Peeling of an Epoxy-bonded. Bonding, Crack Propagation, Damage. For the bond interface during steady-state.

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. Similarly heated elements start at 1500degC and reach 21degC at the end as prescribed. The heat transfer through the body is definitely affected by the -140degC. All predefined fields are set to 21.1 degC including initial base temperature. Temperature dependent properties, constants, etc are all dimensionally consistent.

Could it be the mesh is not fine enough? See attached. UPDATE: I removed all temp dependent properties as a test and still has a similar result with elements dropping below the pre-defined field. UPDATE 2: I noticed my temp dependent properties went up to 1400 degC but temp application of 1500 degC. I applied temp of 1400deg C but still same results with elements dropping below pre-defined temperature field.

Morfeo/Crack is a software product for the computation of the stress intensity factors (SIFs) along the front of three-dimensional cracks and the prediction of crack propagation under fatigue loading using the extended finite element method (XFEM). XFEM is an extension of the finite element method that allows the presence of cracks inside the elements and offers a high precision on the stress singularity at the crack front with special enriched degrees of freedom. Morfeo/Crack for Abaqus is built upon the implementation of XFEM available in Abaqus since version 6.10. The functionality of Abaqus for SIF computation is however limited to the calculation of stationary cracks. Morfeo/Crack for Abaqus enhances Abaqus and is capable of performing crack propagation simulations in complex geometries. The method is based on calling Abaqus/Standard at each propagation step. Between each step, it reads the Abaqus solution, recovers an richer, improved XFEM solution in a small area surrounding the crack using a tailored integration rule, accurately computes the stress intensity factors which determine the crack advance and updates the Abaqus input file with the new crack position.
