摘要:

The Secretary of the British Society for Strain Measurement wishes to point out that the dates of some Regional and Technical Group meetings are subject to final confirmation by speakers. Firm dates are notified in BSSM Newsletter which is sent periodically to members and arrangements can be confirmed by contacting the Regional Secretary indicated or BSSM Office

摘要:

A simple formal method of evaluating principal stresses and directions using eigenvalues and eigenvectors of the stress matrix is presented. The method is equally applicable to 2–d and 3–d stress systems and does much to eliminate any risk of undetected errors in calculation or mistakes in assigning a principal stress to its corresponding direction. The method is extended to analysis of the 45d̀strain gauge ros

摘要:

The effects of the uncertainties associated ith the apparent strain and gauge factor data, given by the manufacturer, in the evaluation of principal strains are examined. Principal strains are obtained by a reduction of the strains measured ith electrical resistance strain gauge rectangular or delta rosettes. The theoretical analysis points out the relevance of the effects caused.

摘要:

This note is aimed at highlighting hat may be inaccurate thinking of the nature of cold (logarithmic) creep ‐ i.e. creep hich may be observed in most steels at room temperature (20d̀C). There is a dearth of information on this topic although engineers have come to regard cold creep as a ‘time dependent plastic’ deformation. As such it is assumed that the assumptions of plasticity are obeyed during the creep p
