摘要:

A brittle coating stress analysis technique applicable to orthotropic materials has been developed. The technique has been applied to a unidirectional glass fibre reinforced epoxy. Its behaviour has been studied under uniaxial and biaxial stress fields using cantilever beam specimens and circular disc specimens under diametral compression. Fibre orientation in the specimens has been varied. In each case it has been observed that the cracks represent the direction of principal strains in the specimen material and not the direction of principal stresses. Application of brittle coating techniques has been suggested to establish the direction and magnitude of principal stresses and strains at every point in a problem with unknown stresses and strains.

摘要:

A transducer is described capable of determining dynamic drag and lift coefficient for bluff bodies in air flow. Such factors and their frequency dependence are becoming increasingly important in the wind excitation of structures.The device incorporates facilities for varying the angle of attack on the model structure surface and although developed for studies on bluff bodies it can be adapted readily to other bodies of uniform section including aerofoil, circular cylindrical, and more general shapes.Dynamic output is derived from electric foil strain gauges and circuitry yielding measurements of good linearity, repeatability and stability.

摘要:

Strains generated during large plastic deformation of diametrically‐compressed rings were measured using surface grid distortions. For rings sufficiently thick in the axial direction, the deformation pattern approximates plane strain bending. A strain/displacement relation is suggested and applications to the study of workability illustrate
