Abstract: In this work, we propose a strength theory as a function of temperature and state of stresses for metals. Based on the fracture in the hydrostatic stress, we derived a generalized strength model, in which the fracture ...

Abstract: Fundamentally understanding the temperaturedependent modulus is the key issue for materials serving in high temperature environments. This paper proposes a model based on lattice vibration theory to predict the ...

Abstract: In this work, we develop an optoelectronic system for in situ observation and measurement in hypervelocity flows. The system has the advantages of strong radiation resistance and self-adaptive exposure time of the cameras. ...
