摘要:

Cold‐rolled, heat‐treated strip has tensile and compressive stress‐strain characteristics which approximate to those of an ideal elastic‐perfectly plastic material. The paper describes the use of Gardiner's1equation for spring‐back following pure bending and its application to a rapid method of determining the ratio of the Young's modulus to the yield stress of the material. If, as is often the case, tension is applied to the strip during coiling, the spring‐back equations of Woo and Marshall2are applied. Woo and Marshall's equations for residual stress are used in non‐dimensional form for both pure bending and bending

摘要:

A non‐stroboscopic system for ‘freezing’ rotational motion, based on an image de‐rotation principle, has been adapted to allow the study of simulated gravity stresses induced in small‐scale models under centrifugal loading. The resulting system proved to be efficient and inexpensive; it performed equally well in reflection or transmission and was thus perfectly suited for photoelastic or moiré fringe investigations in ‘real time’, i.e. by dire

摘要:

In‐situ measurement of concrete strains with acoustic gauges often requires that the gauges are encapsulated or ‘briquetted’ for protection. The effects of age and moisture regime on the response of the briquetted gauge are, however, unknown. Studies extending up to 700 days on these two effects are presented and gauge response is compared to that of the unbriquetted gauge. It is shown that both age and the moisture condition of the briquetted gauge influence its response. By choosing a datum, relevant to their environment and related to some time after the peak of hydration temperature is reached, the response of the briquetted gauge can be made to be close to that of the unbriquetted gauge. Tests show that if this is done the stability and dependability of the briquetted acoustic gauge can be relied
