The schedule for the McMat07 session on dynamic behavior and failure is given below. My talk will be an a flow stress model for high strain rates and high temperatures applied to 6061-T6 aluminum alloy. Hope to see youin Austin.
7-2 Dynamic Behavior and Failure of Materials
Topic Chair: Tracy Vogler, Sandia National Laboratories
Topic Co-Chair: Rebecca Brannon, University of Utah
Hello world!
I’ve been working with SPF analysis
recently. I followed the Abaqus example to solve my problem. But the result for
my pressure cycle isn’t as expected. It should have increased step by step from
the initial stage as in the real process. If it is possible, I will thank any
suggestions from whom related to this kind of simulation.
Abstract |
This paper presents an anharmonic lattice statics analysis of 180 and 90 domain walls in tetragonal ferroelectric perovskites. We present all the calculations and numerical examples for the technologically important ferroelectric material PbTiO3. We use shell potentials that are fitted to quantum mechanics calculations. Our formulation places no restrictions on the range of the interactions. This formulation of lattice statics is inhomogeneous and accounts for the variation of the force constants near defects.
The simple extension tear test-piece also referred to as the trousers sample is widely used to study crack propagation in rubber. The corresponding energy release rate, called tearing energy for rubber materials, was first established by Rivlin and Thomas (Rupture of rubber. I. Characteristic energy for tearing. J. Polym. Sci., 10:291–318, 1953); a second derivation was proposed later by Eshelby (The calculation of energy release rates. In G. C. Sih, H. C. van Elst, and D. Broek, editors, Prospects of Fracture Mechanics, 69–84, Leyden, Noordhoff, 1975).
All metallic, hollow sandwich cylinders having ultralight two-dimensional prismatic cores are optimally designed for maximum thermo-mechanical performance at minimum mass. The heated cylinder is subjected to uniform internal pressure and actively cooled by forced air convection. The use of two different core topologies is exploited: square- and triangular-celled cores. The minimum mass design model is so defined that three failure modes are prevented: facesheet yielding, core member yielding, and core member buckling.
Dear Friends.
I want to simulte the mechanic behavior of of Fiber Reinforced Composites and Textile Reinforced Composites.
Could you give me some advice on which software is suitable?
Thank you in advance
