The use of multiple vendor software products creates inefficiencies and increases costs.SIMULIA delivers a scalable suite of unified analysis products that allow all users, regardless of their simulation expertise or domain focus, to collaborate and seamlessly share simulation data and approved methods without loss of information fidelity.
Abaqus 6.14 Software Products CreatesAbaqus 6.14 Full Vehicle LoadsIn the automotive industry engineering work groups are able to consider full vehicle loads, dynamic vibration, multibody systems, impactcrash, nonlinear static, thermal coupling, and acoustic-structural coupling using a common model data structure and integrated solver technology. Best-in-class companies are taking advantage of Abaqus Unified FEA to consolidate their processes and tools, reduce costs and inefficiencies, and gain a competitive advantage. For example, in the automotive industry engineering work groups can consider full vehicle loads, dynamic vibration, multibody systems, impactcrash, nonlinear static, thermal coupling, and acoustic-structural coupling using a common model data structure and integrated solver technology. A pioneer in the 3D software market since 1981, Dassault Systemes applications provide a 3D vision of the entire lifecycle of products from conception to maintenance to recycling. ![]() I recommend to download as fast as you can or you will lose file you need ( Links dead because of Copyright Infringement ).

In Abaqus, after maximum load, unstable fracture happened but in experimental tests stable fracture continues. I have attached my result in a photo that shows experimental and numerical results.

Abaqus 6.14 Crack Propagation StartsHowever, when I simulate my model every time the crack propagation starts in the perperdicular force direction, but after the steps, the propagation goes to the diagonal and doesnt go back to force perperdicular direction. In the experimental test, the propagation oscillates but keeps the force perpendicular. Someone could be help me What I can do to change this propagation I have already tried to change the boundary condition, but it continues the same propagation.

I am sure that you have choose the Linear for your Softening behavior Maybe its better to use Exponential or Tabular for Softening behavior of your material (In the Damage Evolution part). The second reason might be the non linearity of your material that you have to turn NLGEOM on in the Step modulus. I hope that your problem will be solved Best of Luck;) Cite 7 Recommendations All Answers (19) Deleted profile i think you did not keep non linear geometries ON Cite 1 Recommendation 21st Jul, 2014 Asgar Mohamadzadeh Sahand University of Technology where we can on it Cite Deleted profile in Step module.

You need to check if this criterion corresponds to the physics of your problem. How do you calculate the fracture toughness Is the value you find maybe only applicable to the transition from stable to unstable growth, and should you be using a lower value for stable crack propagation Cite 1 Recommendation 22nd Jul, 2014 Asgar Mohamadzadeh Sahand University of Technology yes i obtain it only for stable crack propogate how can i use it for all dominate more explain Cite 23rd Jul, 2014 Sajith S Indian Institute of Technology Guwahati You may also try the FRANC 2D3D developed by Cornell University, which works great for crack propagation problems. You can download the software from their website. More information at Cite 3 Recommendations 24th Jul, 2014 Karuppasamy Pandian M Sogang University Check your element size, because the crack initiation and crack position varies with element size.Hence, choose appropriate element size by comparing obtained results with other related works. Once you fixed element size properly, the crack will propagate continuously, because crack propagation is a material parameter. However, there is some mesh dependency in XFEM, it will affect your result slightly.
