Hello everyone,

I am getting a strange bug regarding CZM in ABAQUS. I have discrete joints between two copper bars in a DCB sample. I use the interaction module to model the contact in interface between the joint and copper. The contact works pretty well in some of the joints while no contact forms in some other ones especially the leading joint! It means that seperation happens immidiately after job submission. I would really appreciate if somebody can help me with this.

Thanks,

Amir

Good mouring Imechanica's users, i have a question about the cohesive elements and thier embedding in a finite element mesh, i have a 2D mesh created in Matlab with the Nodes numbering and their coordinates and the elements numbering and their connectivities, all these Datas in vectors and matrices, the element type is a four noded linear quadrilateral elements, the mesh is not regular in general, i would like to embed cohesive elements between some or all elements in the mesh, mean that each element is surounded by cohesive zero thickness elements over all its four edges, so could any one

In this 1 hour webinar we will show how the new features and enhancements in TURBOdesign Suite 5.2.5 enable turbomachinery engineers to produce breakthrough high-efficiency designs faster than ever before. Two example cases will cover application of the new features to the full design process from preliminary sizing to automatic optimization.

All vacancies have been fulfilled.

As the largest interdisciplinary collaboration for mechanical engineering, you need to present your research at IMECE.Submit an abstract to present your paper to more than 4,000 attendees from 75+ countries representing more than 20 mechanical engineering disciplines. Include your research in this cross-disciplinary mix to help shape the technical content of the meeting and actively participate in the dialogue.

Latest version of Leading Design for Turbomachinery Suite drastically reduces turbomachinery optimization computational requirements, lower production costs.

XFEM can be used in Abaqus for static analysis. I would like to use XFEM in implicit or explicit dynamic analysis.

I am using Abaqus version 6.13.

XFEM is allowed with static analysis in earlier Abaqus versions (6.9).

Newer versions have implicit dynamic analysis compatiblity with XFEM.

However, when I define an implicit dynamic step,
