Calculated strength of irradiated ferritics

Journal of Nuclear Materials, 1985
Abstract Effects of irradiation on dislocation recovery kinetics and strengthening have been calculated and compared to reported responses in Fe-2 1 4 Cr-lMo steels. The analysis indicates that predicted interstitial loop growth causes increases in strength at 673 K that are comparable to measure increases in strength at 10 dpa.

Strength calculation of cutting tools

International Journal of Machine Tools and Manufacture, 1994
Abstract A review of the basic analytical approaches used for the strength calculation of cutting tools is presented in this article. A new, less labour-consuming and more accessible approach is offered according to which the complicated theoretical models for the determination of the magnitude, region, direction and distribution of the cutting ...

On the calculation of phosphorescence oscillator strength

Monatshefte f�r Chemie, 1980
It is pointed out that one of the two commonly used expressions for calculating the oscillator strength of phosphorescence transitions is incomplete. By using the adequate transition operator, a correction term is added to one of the two expressions which then become analytically equivalent up to second order in the fine structure constant.

Calculations of the strength of the polyethylene molecule

Journal of Polymer Science: Polymer Physics Edition, 1973
AbstractA theoretical determination of the elastic modulus, the breaking strength, and breaking strain is made for a single infinitely long molecule of polyethylene (CH2)∞. These results are compared with those of a similar calculation on a molecule of polyethylene with a side chain attached.

Remarks on the Calculation of Bond Strengths

The Journal of Chemical Physics, 1939
The hypothesis that predissociation as evidenced by sudden broadening of the rotation lines in an absorption spectrum may be used to establish the strength of the bond involved in the associated photochemical act is re-examined. It is shown to lead to incorrect conclusions in the few cases where its use seemed applicable. New values are derived for the

Nomographs for Calculation of Field Strength

IETE Journal of Research, 1969
A method of calculating skywave field strength in tropical region was developed in the Research Department, All India Radio. This is based on results of ionospheric absorption and field strength measurement conducted by the department. In order to enable easy estimating of skywave field strength by this method at any distance, for any mode of ...

CALCULATION OF THE STRENGTH OF CASING COLUMNS

For strengthening the walls of the well with the casing its mechanical properties and rheological parameters of the rocks should be considered. Radius of excited, viscous-elastic rocks and influence of internal friction angle on the strength of the casing have been analyzed in the article.
