the new impact factor for JAM
The 2016 impact factor for Journal of Applied Mechanics has increased to 2.133. This increase is mainly due to the rapid review process, which has led to significant increase of submissions (and significant decrease of the acceptance rate). The average time for the first round of review is < 10 days, and that for the second round of review (if necessary), including both the authors' revision time and reviewers' re-review time, is < 3 weeks.
Recent Work "Modeling the Energy Storage and Structural Evolution during Finite Viscoplastic Deformation of Glassy Polymers"
The enthalpic response of amorphous polymers depends strongly on their thermal and deformation history. Annealing just below the glass transition temperature (Tg) causes a large endothermic overshoot of the isobaric heat capacity at Tg as measured by differential scanning calorimetry, while plastic deformation (cold work) can erase this overshoot and create an exothermic undershoot. This indicates that a strong coupling exists between the polymer structure, thermal response and mechanical deformation.
Looking for Postdoc position in Mechanics
Hi, I am looking for the post-doctoral position in structural dynamics ( instability of the thin structures, shell theory, composite structures, static and dynamic buckling of the shells). I am currently a Ph.D. candidate in the Nonlinear Mechanics Laboratory at Indian Institute of Tehnology Kanpur (India) where Dr. Pankaj Wahi and Dr. Sovan Lal Das have adviced my research for the past four years. My PhD thesis deal with the shell theory and dynamic behavior of the shell ( especially thin-walled circular cylindrical shells).
ADT launch TURBOdesign Suite v6.3 Via Webinar
This webinar will highlight some of the key new functionality enabled by the updates, as well as showing a live demonstration of a single stage centrifugal compressor stage consisting of impeller, vaned diffuser and return channel/de-swirl vane.
contact element
Hi friends;
I built a model in solidworks and Imported it in ansys workbench for modal analysis. In ansys workbench my model has many gaps; therefore many contact and target elements are defined. In ansys workbench bonded contact element is defined. Do effect bonded contact and target elements on frequencies and modeshapes in my problem? Do change bonded contact and target elements frequencies and modeshapes?
please help me.
Regards.

Is DDSDDE needed to be rotated by DROT or not in Abaqus UMAT?
I am trying to formulate UMAT subrouting for crystal plasticity. DDSDDE is required to be rotated by DROT or not for anisotropic material?
Post-Doc position within the International Research Training Group "Integrated Engineering of continuous-discontinuous long fiber reinforced polymer structures” (DFG GRK 2078)
The international research training group "Integrated Engineering of continuous-discontinuous long fiber reinforced polymer structures” offers one post-doc position at Karlsruhe Institute of Technology (KIT). Discontinuous long fiber reinforced polymer structures with local continuous fiber reinforcements represent an important class of lightweight materials. This class of materials has a significant potential for energy savings due to the high specific stiffness and strength as well as the variety of design options in diverse technical applications, e.g., in vehicle construction.
Evaluation of J-integral in a 2D non-linear Abaqus model
Hi guys,
Does anyone know the input file command line to carry out the J-integral evaluation in an XFEM crack propagation simulation?? Documentation is not clear and keeps giving errors when I run a job.
