✦ Synopsis

An interpretation is given of the observations of the continuous solar radiation in the spectral range 600-1700 A. The model allows for deviations from LTE of H, C, Si and S, and is in hydrostatic equilibrium. The predicted intensity from 1680 to 1520/~ has virtually no dependence on the electron temperature variation in the optical depth range 10-3-4 • 10 -2, at 5000/~; the brightness temperature is compatible with a low electronic temperature minimum near the optical depth 10 -4. The model of the low chromosphere is characterized by a steep temperature gradient. The model satisfies observations at millimeter wavelengths.

This paper presents a modified Weibull stress model which accounts for the effects of plastic strain and stress triaxiality at the crack tip region. The proposed model is applied to predict cleavage fracture in a modified A508 pressure vessel steel. It is demonstrated that the Weibull modulus (m) re
