To use cohesive elements, normally user can add a layer of elements between neighbouring node pairs. This matlab code can help you to process that especially your FE mesh is irregular. The code, the initial .inp file and corresponding out put files are attached for a better illustration. The new generated cohesive elements won't cause any trouble in the element number. Also you can apply this code to generate new UMAT elements in mesh.
I am confused in using numerical schemes: What can convergence of a numerical scheme tell us and what not??? lets assume that a numerical scheme does converge to "A result" or "A number", but how could we be sure that the scheme has actually converged to the "RIGHT solution" and not a WRONG one??
Project Title: Design and Development of High Performance Composites for Hydrocarbon and Water Transmission & Distribution Systems: An Integrated Approach
Advanced Materials and Multi-functional Structures (AMMS) group at Masdar Institute invites applications for Project-Postdoctoral Positions to work on a multi-disciplinary collaborative project funded by GASCO (ADNOC), Abu Dhabi. Principal Investigators of the project are:
• Prof. Kumar Shanmugam, Principal Investigator, Masdar Institute (MI)
I have a bicrystal with 2 material orientations in Euler Angles. How do I assign them to my Abaqus Input file? I am using Dr Huang's code for CP. After going through several forums, I understood that I have to create a card with *ORIENTATION entry.
I wonder how important the initial set up for a Smoothed Particle Hydrodynamics simulation is. Is the initial particle distribution somehow significant for the final result? How to control particle density and distribution along problem domain? What are the important factors inherent to the initial set up? Having control over the initial set up is going against the philosophy of this method?
I recently took over as the ESIS blog editor. Being the second in this baton relay, I will do my best to live up to the good reader expectations that has been established by my precursor, who is also one of the instigators of the blog, Wolfgang Brock.
I post the links to some of our recently published papers on magneto-elasticity. These are iron-filled elastomers whose mechanical properties can be influenced by the application of a magnetic field. A continuum theory that accounts for magneto-mechanical coupling as well as rate-dependent energy dissipating deformations is presented.
I also attach post-print versions of these articles here. Hopefully, they can be useful for some people working in this field.
Case Studies in Engineering are a series of open access journals, which publish practical outcome of research and indusrty projects in a variety of Engineering disciplines, including: Construction Materials, Fire Safety, Structural Engineering, Engineering Failure Analysis, Mechanical Systems and Signal Processing, Nondestructive Testing Evaluation and Thermal Engineering.
Dear all, I am an applied mathematician and I have been stucked by the this general question for a while, i.e., to determine the stiffness matrix of transversely isotropic material from known strain and stress tensors. The definition of transversely isotropic tells us that the stiffness matrix can be defined by 5 constants, see attached figure. C44 is easy to determine, so we can focus on the remaining 4 constants. I attempted to establish 4 linear equations for these 4 constants with the known strain and stress components.
