Shell element transverse shear stresses in ABAQUS VUMAT
Hi Everyone,
Hi Everyone,
when trying to submit a model for analysis i recieve an error as follows
1200 elements have missing property definitions. The elements have been identified in element set ErrElemMissingSection.
Error in job 4: Analysis Input File Processor exited with an error.
Job 4 aborted due to errors.
I have defined the material and then seeded it and defined the element before meshing it.I have also tried defining the element before defining the material and still get the same error.
I am currently seeking for Chinese PhD applicants (now residing in Mainland, China) to work in the experimental characterisation and numerical modelling areas of nanomaterials/polymer nanocomposites at Department of Mechanical Engineering, Curtin University of Technology, Australia. Please see my departmental webpage for any further enquiry (http://mech.eng.curtin.edu.au/dong/index.cfm). The specific research projects can be discussed in contact for the joint research interests.
dear everyone,
I want to ask if anyone deal with strain gradient proposed
by fleck eat. in 1994 and 1997, using subroutine in ABAQUS ?
Hi everybody,
I modeled a sheet metal forming process in which entire blank is partitioned into two regions (Central and exterior regions). Forming tool is considered as a 3D-Analytical rigid body (Revolved Shell) and partitioned into two regions too. According to this process, the head of punch should be tied to the central region of the blank and punch's walls should contact with exterior region.
In interaction module, I can’t select defined regions on forming tool separately as the surfaces and I don’t know why the whole surface of the punch is selected?
In a lithium-ion battery, both electrodes are atomic frameworks that host mobile lithium ions. When the battery is being charged or discharged, lithium ions diffuse from one electrode to the other. Such an insertion reaction deforms the electrodes, and may cause the electrodes to crack. This paper uses fracture mechanics to determine the critical conditions to avert cracking. The method is applied to cracks induced by the mismatch between phases in crystalline particles of LiFePO4
Dear All
I got the following error msg in Compaq Visual Fortran.
forrtl: severe (170): Program Exception - stack overflow
How to solve this problem?
Best Regards

Programs from Programming the Finite Element Method by Ian M. Smith and D. V. Griffiths are downloadable from: www.mines.edu/~vgriffit/4th_ed/Software This title demonstrates how to develop computer programmes which solve specific engineering problems using the finite element method. It enables students, scientists and engineers to assemble their own computer programmes to produce numerical results to solve these problems.
Please allow me to note that I have recently published in Philosophical Magazine a paper that presents a general approach to Gibbsian surface thermodynamics that includes a treatment of solid surfaces. It can be accessed through the following link:

Many granular materials encountered in engineering practice are of irregular shapes that are not essentially smooth or rounded. However, in DEM, grains are idealized as spheres and ellipsoids and their surface are assumed to be sufficiently smooth. As a result, I wonder why there is no model of irregular shapes and what is the difficulty on implementing such a model? Is there any recent work aimed to simulate grains of irregular shape? Thanks a lot.
