Good morning,
I am using franc2d and I would like to know how can I apply a residual stress field. The manual that I have states that I have to write an ASCII file with the extension *.rsi from the option residual load.
Does anybody know how can I write such file in order to input my residual stress field or has anybody an example file?
Is it also possible to apply another load with this residual stress field after inputting the residual stress field?
Thanks a lot,
Sguaiz

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).
