In this paper, the authors present work that was carried out to develop an m-learning extension to a Moodle based VLE at the University of Colombo School of Computing (UCSC) and its initial evaluation. They believed this new development could bring a

Common methods of estimating the Weibull modulus are surveyed. Computer simulation is used to obtain the statistical properties of different estimators. Most estimators are shown to be biased and their respective adjustment factors, for a range of ex

The failure probability of a brittle material stressed in a tensile biaxial loading system is investigated. A “failure diagram” relating the two mean biaxial stresses is mapped out for different values of the Weibull modulus as a function of volu

Weibull analysis for the interpretation of strengths of brittle materials was previously justified for a particular flaw size distribution. The present results show that the Weibull distribution provides a close approximation to the distribution of f

A general expression for the failure probability of a brittle material is developed by using the properties of flaw size distribution and the stress necessary to fracture an inclined crack. A comparison is made with Weibull analysis and an expression

Publisher Summary This chapter discusses the determination of crack growth in a mixed mode. Studies on the propagation of cracks under an applied load are not readily analyzed when the cracks are not lying perpendicular to the applied stress. When a
