Qian Weichang passed away on 30 July 2010.
He was 98.
Qian, a pioneer in mechanics and applied mathematics in
modern China, was one of the three famous "Qians" in China's science and
technology field. He was well known alongside Qian Xuesen, the father
of China's space program, and Qian Sanqiang, a nuclear physicist who
oversaw the development of China's nuclear program.
I am PhD of 2008 and looking for PDF in my working areas as mentioned above or other related areas. My email is umesh_rrl [at] rediffmail.com (umesh_rrl[at]rediffmail[dot]com)
Although the nineties witnessed an intensity of research on nanocrystalline metals owing to their ultra-high strength, the early enthusiasm was met with severe disappointment due to their brittle nature and loss of structural stability. In contrast, research over the past few years has provided compelling evidence that nanotwinned structures may be the optimal motifs for the design of both high-strength high-ductility materials.
The Interdisciplinary Centre for Advanced Materials Simulation (ICAMS) is a new research centre at the
RuhrUniversity Bochum, Germany. At ICAMS an interdisciplinary team of scientists from engineering,
materials science, chemistry, physics and mathematics is working on the development and application
of a new generation of simulation tools for multiscale materials modelling.
Hello,
I am a Masters student and I need to model a spring shape memory alloy in ABAQUS. I have found a UMAT file,however the file contains the geometry of a 1X1X1 cube. Does anyone have any idea of how I could copy the geometry of the spring(which i modeled in solidworks and imported to ABAQUS)into the input file of the cube,so that I could run the model in ABAQUS. I have tried this but ABAQUS is giving me errors
Or does anyone have any other idea of how I could model a Sping SMA in ABAQUS?
Thanks
Akin
Hi,
I'm looking to solve a problem in which although the position of a boundary or force-generating constraint is not known, the distance between the constraint and one other (usually a "neighbouring" particle -- whatever neighbour means ;) ) is known.
After much thought, I've concluded that the problem is a constrained energy-minimization problem. In other words, I need to find the arrangment of the particles such that the strain energy of the system is minimized and while constraint between the nodes is satisfied.
I'm looking for the thermo-mechanical properties of aluminum, such as Young modulus, thermal expansion coefficient, thermal conductivity coefficient and poisson ratio as a function of temperature :
E=E0(1+E1*T+E2*T^2+E3*T^3) ; T: temperature in K
Hello.
I am new in both iMechanica and ABAQUS and I would need help:
Postdoctoral and Graduate Assistant Positions are
immediately available to work on phase-field simulations of phase
transformations and microstructure evolution in metallic alloys or
oxides. Strong background in mechanics and thermodynamics of of solid
microstructures is a plus. If interested, please email a resume to
Professor Long-Qing Chen, Penn State University at lqc3 [at] psu.edu
