Ferroelectric materials, such as PZT, PLZT and BaTiO3, are being considered, or are already being employed, for a large number of applications including nanopositioning, high speed valves for fuel injectors, ultrasonic transducers, high speed camera shutters and auto focusing mechanisms, energy harvesting, and pico air vehicle design. Their advantages include nanometer positioning resolution, b...

A model for creep threshold stresses in alloys strengthened by coherent, misfitting precipitates is developed for the case where the precipitate is not sheared, and where there are elastic interactions between a dislocation and the precipitate over which it climbs. Calculations of the particle stress field due to a positive stiffness and lattice parameter mismatch between precipitate and matrix...

The description is given of a model for concrete in compression at elevated temperature that incorporates elastic, plastic and creep strains as functions of the temperature and stress history. The plastic strain and the creep strain depend on the stress history and the stiffness of the model depends on the load level during fire exposure. The proposed model is an updated version of a model pres...

We study the creep motion of an elastic string in a two-dimensional pinning landscape by means of Langevin dynamics simulations. We find that the velocity-force characteristics are well described by the creep formula predicted from phenomenological scaling arguments. We analyze the creep exponent mu and the roughness exponent zeta. Two regimes are identified: when the temperature is larger than...

A 2-yr study was conducted to evaluate the effects of a high-energy creep feed, preweaning zeranol implants and breed type on calf and cow performance. Two hundred calves sired by Brahman and Romana Red bulls out of Angus and Angus x Brown Swiss reciprocal crossbred (F1) dams were stratified by breed type and sex to three creep treatments: no creep feed (NC); long-term creep (LC), creep-fed fro...

This paper discusses recent theoretical developments on fracture at elevated temperature in the presence of overall plastic (dislocation) creep. Two topics are considered: 1. Stress fields at tips of macroscopic cracks in creeping solids: Here consideration is given to the transient development of an effectively steady state of creep in a cracked body, following sudden load application for whic...

Creep deformation in < 001 > oriented single crystals of CMSX-3 has been studied at temperatures around 850°C at a stress level of 552 MPa. Detailed observations of the evolution of the dislocation structure during creep have been made. TEM stereo pairs show creep deformation in the matrix phase, leaving the 7’ precipitates undeformed. In previously undeformed crystals there is a brief incubati...

A total of 84 sows (PIC Line 1050) were blocked according to day of farrowing and parity and allotted in a 2 x 2 factorial arrangement of treatments with lactation feed intake (ad libitum vs. restricted) and creep feeding (no vs. yes) as factors. Sows fed for ad libitum intake (ad libitum-fed) were allowed free access to a common lactation diet (3,503 kcal of ME/kg, 0.97% standardized ileal dig...

a r t i c l e i n f o A powerful and robust numerical homogenization method based on fast Fourier transform (FFT) is formulated to identify the viscoelastic behavior of calcium silicate hydrates (C-S-H) in hardened cement paste from its heterogeneous composition. The identification is contingent upon the linearity of the creep law. To characterize cement paste microstructure, the model develope...
