...Qian Wu; Yong Wang; Tao Han; Hongtao Wang; Laihui Han; Liangliang Bao The tensile tests of body-centered cubic (BCC) Fe nanowires were simulated through molecular dynamics methods. The temperature and strain rate effects on the mechanical properties as well as the orientation-dependent plastic...

... structural materials for very high-temperature reactors (VHTRs) due to their exceptional high-temperature mechanical properties. The current creep experiments were conducted at 900 °C for the effective stress range of 15–35 MPa. For both alloys, complete creep strain development with primary, secondary...

...A. Goel; Y. Wen; J. Hein; M. Negahban; J. A. Turner The development of anisotropy as a result of isothermal plastic deformation below the glass transition temperature is investigated for different deformation temperatures. Initially, isotropic polycarbonate was subjected to different extents...

... and nanosystems. In this paper, the framework of higher-order strain gradient plasticity theory with interfacial energy effect is used to investigate the coupling of interfacial energy with temperature and how it affects the initial yield strength (i.e., onset of plasticity) and the strain hardening rates...

...Ajit K. Roy; Joydeep Pal; Muhammad H. Hasan The role of temperature and load ratio ( R ) on the crack propagation rate ( d a / d N ) of Alloys 276 and 617 under cyclic loading was investigated. The results indicate that the rate of cracking was gradually enhanced with increasing temperature when...
