Writing of this book was motivated by the lack of readily available design data for use in the design of pressure vessels, boilers, reactors, autoclaves, with varied cross-bore entry geometries and thickness ratios. The cross-bores include tee-offs or openings on the sides or end covers. The results presented form a quick design aid when engineers need to consider: elastic stresses; stress concentration factors; autofrettage; residual stresses; service stresses. This data will be very handy and save time that would be required to develop and run a computer program for analyzing the problem....

The use of High Density Polyethylene (HDPE) lining in seepage prevention in dams was identified to reduce the cost of water storage. To make it acceptable to end users, it is necessary to determine its lifespan when exposed to tropical climates using viscoelastic models. The Findley Power Law was used to build a model for prediction of the material behaviour at elevated temperature in both short term and long term applications. Time-Temperature Superposition (TTSP) was also used to develop master curves for prediction of long term properties. Micrographs were presented to track the changes...
