摘要:

The Hon. Secretary of the British Society for Strain Measurement wishes to point out that the dates of some of the BSSM meetings in the Diary are provisional and that further meetings may be announced in some regions. Firmer details will be available in due course from the BSSM office, 281 Heaton Road, Newcastle upon Tyne NE6 508 (Tel: 0632 655273) or from the regional organisers indicated in the Diary. Numbers shown in parentheses at the end of a BSSM meeting announcement e.g. (2.30) refer to modules in the BSSM Certificate Scheme. Details of the scheme are available from the above address.

摘要:

The necessity for reliable shakedown/ratchetting data for stainless steel type 316 arises from its widespread specification in nuclear power plant. In such applications this material is required to operate at temperatures of about 500d̀ C. This paper details an experimental technique which permits such shakedown/ratchetting tests to be undertaken at elevated temperatures

摘要:

Using a two‐dimensional photoelastic technique, hole shapes have been optimised in diametrically loaded circular discs with two neighbouring holes leading to minimum s.c.f. Results are given for a range of disc diameter/hole diameter ratios (15.39 $ D/d $ 3.74). In comparison with circular holes, the s.c.f's have been reduced upto about 21 per cent at regions where peak stresses act. The results include the stress distribution around the holes, optimum geometries developed and the effect of tilting the load directio

摘要:

Conventional polariscope set‐ups like the plane polariscope or the dark or bright field set‐ups specify the positions of the various optical elements with respect to the polarising axes of the photoelastic model for determining the isoclinic and isochromatic parameters.In this paper, it is shown that such specification is not necessary since, for any light path, the positions of the optical elements for an absolute minimum in intensity of the light emerging from the analyser are unique. To illustrate this, the case of a general retarder introducing a retardation 2δ at an azimuth θ with respect to the axis of the polariser is discussed and the conditions for the determination of the isoclinics and isochromatics are obt

摘要:

Operator fatigue and eyestrain arising from prolonged use of a computer or other visual display unit (VDU) can be eliminated by fitting a circular polarising filter over the screen.
