You need to go to results of your job and under Node Sets and under Node Sets you should find your "ErrNodeMissingDofConstrDef".

textbook FEA of Composite Materials Using Abaqus

Wed, 2019-11-06 08:05

In reply to I'm a student in the States

Although emphasis is in orthotropic and laminated materials, you can use most of the book, including many examples, to learn Abaqus/CAE. Many users have said it helped learn Abaqus even though they were not that interested in Composites but somethig else. Model generation, elements to be use, an so on are common for all applications of Abaqus. Ch. 2 Intro to FEA. Ch. 3 Elasticity. Ch. 4 Buckling. Ch. 5 deals with 3D stress, Ch. 6. also 3D, Ch. 7. viscoelasticity, Chapters 8 and 9. damage, and Ch. 10. delaminations. There are many solved examples with pseudo-code that you can follow to do the examples in Abaqus/CAE.

In reply to How do I count Keyword Blocks in the Abaqus input file?

I tried counting the lines that start with a single *. Not high enough. 

I counted all the lines except nodals coordinates, elements, and comments. Too many. 

I counted all the lines except actual nodals coordinates (counted *nodes), element conectivities (counted*element), comments, and *end part, *end assembly, etc. Too many. 

What could it be?

In reply to PhD position openings

We are looking for two motivated PhD students to join us in Spring 2020. The successful candidate should have a strong background in continuum mechanics and be proficients in programming. Please take a look at the attached descriptions. 


Excellent and timely summary

In reply to Journal Club for October 2019: A Metamaterial Approach to Soft Robotics

Dear Katia,

Thanks for this excellent and timely summary of the mechanics of metamaterials for soft robotics. I am new to this area and would like to learn more about it. I hope to hear your feedback on a few questions:

1. What will be the most promising applications of soft robotics in the next few years?

2. What are the size limits of the metamaterials for soft robotics? Since most materials/structures are soft, will they have problems to design large scale structures (i.e., reconfigurable infrastructures)?

3. Many biological structures, including human bodies, are composited structures with hard and soft components. Will new opportunities emerge for robotics with similar integration of hard and soft parts by leveraging the widely studied and used hard/rigid robotics and recent progress of soft/deformable robotics?

4. You described various output can be achieved for some simple input for soft robotics. This poses great challenges in the control schemes. Are the current control schemes in the rigid robotics able to handle the control of soft robotics? If not, what will be the new direction for the development of proper control methods for soft robotics? 



this problem in the meanwhile was solved by Persson in 2007.

In reply to Surface Roughness and Electrical Contact Resistance

See e.g. our paper on load-separation curves, which, by differentiation, lead to linearity between contact stiffness and load, and hence also conductance and load

A letter to the Editor of Nature has been accepted on this

In reply to The false myth of the rise in Italian self-citations, and the impressively positive effect of bibliometric evaluations on the increase of the impact of Italian research

I am pleased to inform you that the Editor of Nature has accepted a commentary on this findings for the next issue of Nature.

I have also launched a petition on the "excellent researchers" in Italy at the link

The idea is to have a next round of assessment of "excellent researchers" (for example as included in the list of the 100k best scientists published by Ioannidis et al in Plos Biology) and allocate directly some resources for their promotion on the italian university system should be interested.
