Thermal buckling analysis of a radially graded annular FG plate with temperature dependent properties

Submitted by omidomid on

Dear all

I'm working on the thermal buckling analysis of a radially graded annular FG plates with temperature dependent properties.

The results show that the temperature dependent thermal buckling loads are greater than those of the temperature independent, but I have expected for vice vesa results!

Can anyone explain it ?

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.

Journal Club August 2010: Deformation Mechanisms in Nanotwinned FCC Metals

Submitted by Yashashree on

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.

Modelling a spring shape memory alloy

Submitted by akinbala on

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
