Dear Colleagues:
We are pleased to announce a mini-symposium on Fracture Mechanics at the 52nd Annual Technical Meeting of the Society of Engineering Science, to be held at the Texas A&M University, College Station, Texas, October 26-28, 2015.
School of Mechanics and Engineering, Southwest Jiaotong University (西南交通大学力学与工程学院) has always paid great attention to the development of its faculty group. We are actively recruiting talents in all fields of mechanics, including (in order of priority) Fluid Mechanics,Dynamics and Control,Solid Mechanics and other related fields.
Requirements:
1. A Ph.D. in Mechanics, Material, Mechanical Engineering or related field.
2. A good record of publications.
3. Strong verbal and written communication skills.
On behalf of the International Institute for Multifunctional Materials for Energy Conversion (IIMEC) and the Department of Mechanical Engineering at Aristotle University of Thessaloniki, we would like to announce a summer school on Advanced Material Systems: Experimentation and Modeling. The summer school will be held from July 13–18, 2015 on the Aristotle University campus in Thessaloniki, Greece.
In this work, we present a modified two-mode phase-field crystal (PFC) model for nano-structural evolution of materials. The model is used to study both the face-centered cubic (FCC) and body-centered cubic (BCC) orderings, as well as the solid–liquid coexisting phenomenon. This two-mode PFC model incorporates three parameters in its formulation and damps out the dynamics of the system, except near the first two critical wavelengths.
The sad news is that a large percentage of implants contain cracks which have the potential of causing fracture after fatigue growth. This is the outcome of the present study in which a 100 implants were examined, all apparently intact, having been extracted for various reasons, most likely biological but definitely not mechanical.
It seems that the whole field of dental implants, which is growing very fast, needs a serious mechanical re-assessment, from the design stage all the way up to surface roughening.
Comments are welcome
Hi,
Does anyone know how to compiler an umat in c/c++ for abaqus under windows system?
The Umat wrote in fortran works well, but I do prefer using c/c++ to make program.
I have installed visual studio 2010 c++, intel fortran.
Or is it possible to use c/c++ for umat?
Thanks in advance.
In this work, we developed a conductive silver nanowire (AgNW)-PDMS composite thin film for a flexible strain sensing application. The piezoresistivity of AgNWs-PDMS nanocomposite thin film was experimentally investigated and analyzed by a computational model. The strain sensor shows a strong piezoresistivity with an average gauge factor in the ranges of 1.6 to 14 and a high stretchability up to 70 %. We found excellent agreement between our experiment and simulation results.
We developed highly stretchable, flexible and very soft conductors based on the carbon nanotubes (CNTs)-silicone rubber (Ecoflex®) nanocomposite thin films. The resistance of the CNTs-Ecoflex nanocomposite thin film was recovered to its original value under cyclic loading/unloading for strains as large as 510%. Failure strain of the CNTs-Ecoflex nanocomposite was measured to be about ~ 1380% showing its ultra-high stretchability and robustness.
In this work, we develop high flexible and compressible porous PDMS structures by using sugar cubes as templates. Force sensitive resistor (FSR) sensors were fabricated by the filtration of the CNT solution inside the porous structure of PDMS. We found that sufficient acid treatment can increase the adhesion between CNTs and PDMS. FSR sensors respond the applied pressure and compressive strains by high linearity (R2>0.97) and sensitivity (GFs>2) with a reliable manner.
