摘要:

The paper examines the computational techniques of Mendelson1and that proposed by Moreton‐Moffat2to derive post yield stresses from strain gauge readings and compares them with the fundamental Prandtl‐Reuss approach. Although the approach by Mendelson is extensively used in one form or another in elasto‐plastic analysis its application in the experimental stress analysis field is less common. Moreton‐Moffat highlighted this application and modified Mendelson's method claiming that it was unnecessary to use the post yield constitutive law. In this latter respect their approach is shown in general to be inadequate. The technique based on the Mendelson approach1is found to be an accurate and useful solution especially when modified to incorporate the slope of the constitutive law at the mean stress of any particular finite step. Although the method is an approximate strain analogue of the Prandtl‐Reuss equations the approximation is excellent for practical s

摘要:

A data collection system is described which utilizes the products of separate manufacturers to give a cheaper and more flexible system than could be achieved by buying a single ‘all in’ package.A description of the software requirements of such a system is given along with a description of its use in a typical logging applicat

摘要:

A new Moiré method is proposed to map partial slope contours of laterally loaded reflective plate models. The beam of light reflected by the plate is collected by a field lens and is optically sheared by a thin glass plate at the focus to produce slope modulated gratings at the image plane. No real grating is used. Sensitivities an order higher than those of classical Moiré methods are obtaine

摘要:

Moiré fringes are represented as vectors and their characteristics established using vector algebra. It is shown that the Moiré fringe vector of deformation is the vector sum of those due to extension and rotation
