A new postdoctoral position in continuum mechanics is available at the Weizmann Institute of Science. Candidates should have a strong background in physics and/or theoretical mechanics, as well as experience with analytical and computational methods for solving partial differential equations. Possible projects include the mechanics of frictional sliding, the mechanics of biomaterials, the mechanics of glassy materials and dislocation-mediated plasticity. Highly motivated candidates are requested to send their CV, publications list and statement of research interests to Dr. Eran Bouchbinder eran.bouchbinder@weizmann.ac.il

I will be teaching a sophomore level class  mechanics of materials class.  The class will cover mechanics of basic strength of materials (e.g. beams, pressure vessels), but I also want to teach basic elements of failure mechanics (fracture, fatigue, plasticity, and wear.)  I'm looking for a recommendation of an undergrad mechanics textbook that covers the fracture, fatigue, plasticity, and wear.  The students will have had a statics and mechanics class and their textbook already covers strength of materials.  Thanks.

Good Time to Everybody, I am working on Thermoplasticity, especially thermoviscoplasticity, will be comparing the results of some basic examples problem worked be Simo and Miehe, modelled in Abaqus with the results of a locally developed code. I am new comer in this excellent forum and I am happy to see myself among a nice community of Mechanicians. I regard all those who are conneted in this form and those who helped in connecting this chain of  Mechanics.

 Results are presented on the evolution of subsequent yield surfaces with
finite deformation in a very high work hardening annealed 1100 aluminum
alloy. In Part I [Khan, A.S., Kazmi, R., Stoughton, T., Pandey, A.,
2009a. Evolution of subsequent yield surfaces and elastic constants with
finite plastic deformation. Part 1: a very low work hardening aluminum
alloy (Al-6061–T6511) 25, 1611–1625.] of this paper, similar results are
presented for a very low work hardening aluminum alloy.

This is a review on ductile fracture committed to the Advances in Applied Mechanics (Vol 44). Part of the review has an educational purpose and, as such, is intended for advanced undergraduates and starting graduate students. The other part is an account of recent research conducted in the field.

Though quite long, the review is by no means exhaustive. As noted in the discussion, many valuable contributions to this field have been left out. The focus was laid on micromechanics-based approaches to connect to microstructural aspects in engineering materials.

 I will try to post the electronic PDF once I get permission from Elsevier. 

hi friends am doin my my project on" FEA of plasticity induced crack closure". my specimen size is 80*80 mm. by using symmetry condition i modelled 1/4th of model in ANSYS. therfore i created 40*40 mm plate. with initial crack length of 4mm.means its MT specimen of 80*80mm with 8 mm crack length, by symmetry condition i modelled 40*40 with 4mm crack lenth.

Hi viewers,

I am working with  abaqus 6.7 software. I wish to simulate uni-axial tension and compression cyclic analysis. My objective is to predict the response of steel subjected to cyclic load and in particular, to predict ratcheting effect. I am also interested to draw S-N curve, stress-strain curve, ratcheting behaviour, etc. from the result of the analysis. I tried to simulate an axi-symmetric model and job submission is successfully completed. But I am not aware of the fact that how the  results of analysis can be retrieved to draw the above mentioned curves, please specify how the 'no.of cycle' data can be obtained.

I am working on plastic behaviour of metal. I am using Abaqus 6.7 for simulation of uniaxial ratcheting of steel under cyclic loading. Modelling and job submission/completion has been done successfully. But I cann't understand  where  the data for Stresses(S) &  number of cycle(N) is strored to draw S-N curve. Please suggest.

Hi all,

Concrete is sensitive to strain rate. I want to create a model for a reinforced concrete plane frame. The material model used for concrete is concrete damaged plasticity, and the element type is B21. I want to consider strain rate effects of concrete(strength). The problem is that ABAQUS can not work after considering strain rate effects of concrete when the concrete yields. Can you help me? Thank you in advance.

ello all,

I am an M.S student, my subject in modelling of high strength concrete column under eecentric loading. I made a model of reinforced

 concrete column with in ANSYS by solid65 to represent concrete and link8 for steel.

My model is 200*200*4000 mm, i choose multi., conc.,and elastic linear for concrete, closing crushing for it, for steel bilinear, elastic.

Slenderness ratio (l/d)=20 Although Using large displacement analysis option, model give me very small displacement (less than
