The formation of two misfit edge dislocations is theoretically investigated in the interfaces of a layer embedded in a semi-infinite matrix. Assuming the matrix–layer interfaces are partially coherent, the energy variation resulting from the formation of the dislocations from the lateral free surface of the structure has been determined in the shearing stress field due to the partial misfit. The mechanical stability of the structure is analysed with respect to the dislocation formation as a function of the size of the coherent region of the interface and the misfit strain. 相似文献

A series of experiments was conducted to investigate sex, housing conditions, and strain as possible factors influencing the interference effect of prior exposure to shock on shock-induced aggression. In albino subjects, female rats and rats housed in community cages evidenced the greatest suppression in aggression following prior exposure to shock. In addition, ten sessions of prior exposure to shock produced a greater suppression in shock-induced fighting than 20 sessions of prior exposure to shock. The prior shock effect was not obtained with hooded subjects. Responsivity to shock was also investigated to determine whether the prior exposure to shock attenuation of shock-induced fighting was a consequence of reduced activity in response to shock. Responsivity to shock measured with an isometric platform accounted for less than 4% of the variance in shock-induced fighting in the single experiment that obtained a correlation between responsivity and shock-induced aggression. 相似文献
