Experimental Validation of a Probabilistic Fracture Mechanics Model
A method is developed for validating a probabilistic fracture analysis code (PROFRANC). The method is based on classical statistical techniques and experimental data. It is shown that...
On a Procedure to Estimate the Reliability of Mechanical Components
A procedure, based on the response surface concept is suggested to estimate the failure probability of mechanical components and structures under static as well as dynamic loading conditions....
Pre-Test Selection of Static Force and Displacement Measurement Locations for Damage Assessment
An incomplete set of static force and displacement measurements are used for parameter identification of linear elastic structures at the element level. Measurement locations and the level...
Case Studies of Semi-Closed Pipeline Systems for Flexible Deliveries
The semi-closed pipeline system using the best aspects of the open and the closed pipeline systems, has many applications. It is the best adapted system for use with the variable flow...
Pile Installation and Testing at Ningbo Port, China
As part of an ambitious development program at the Port of Ningbo, the People's Republic of China constructed a 694 m (2277 ft) long offshore pier structure to provide a container berth...
Critical Public Issues for Well Head Protection
New Jersey adopted in 1991 a Well Head Protection Program Plan to provide added safeguards to water supply wells. Through extensive public participation efforts the Department of Environmental...

Consistency and Fairness in Geotextile Specifications
By clearly defining required material properties in terms of 'Minimum Average Roll Values' for routine quality control tests and 'Average Test Values in the Weakest Principal Direction'...
Effects of Liquefaction on Lateral Pile Responses
The potential significance of the impact of liquefaction on the dynamic response of pile foundations has been studied through a numerical study. Results of this study demonstrated that...
Application of Fracture Mechanics Methodology to Assessment of Weld Defects in Offshore Platforms
This paper demonstrates an application of both deterministic and probabilistic fracture mechanics methods to assess weld defects in an offshore platform. The results of the assessment...
A Fourier Series Solution to Bottom Roughness Induced Stresses During Pipe Laying
Often during installation, a subsea pipeline must be laid along seabed portions with rough profiles. The pipeline is forced by the bottom irregularities to bridge across consecutive protuberances....
Stability of Cable-Stayed Brides
This chapter deals only with stability under static loadings. For aerodynamic stabilities and stability of structure under seismic loading, see the appropriate chapters. Both the towers...
Analysis of Soil-Stress Cell Interaction
Static loading experiments conducted on a soil stress cell embedded in a sand are presented. Stress cell performance was evaluated by comparing the indicated stress against the expected...
On the Constitutive Behavior of Single Ice Crystals Due to Dislocation Mechanisms
A three-dimensional constitutive relation is derived for single ice crystals. The formulation is developed in terms of dislocation processes on the basal, prism, and pyramidal planes....
Microstructure and Mechanical Behaviour of Ice
Short descriptions are given for ice in nature, test methods used to evaluate their deformation behaviour and, a general microstructure-based constitutive equation. Equations suitable...
Fractal Crushing
This paper develops an approach to a two-dimensional fragmentation process, in which floating ice floes are driven against each other and break up into smaller floes. It first considers...
Size Effects in the Fracture of Quasi-Brittle Materials
Causes and influences of the structural size effect that is exhibited by materials such as concrete, mortar, ice rock and ceramics, are discussed. The size effect law, which models this...
Some Questions on Fracture Mechanics of Ice and Ice Covers
Investigation of natural processes of deformation and fracture of ice covers, and processes of its interaction with icebreaker or ice-resistant structures requires as a rule considerations...
Effective Pressures Measured During Indentation Tests in Freshwater Ice
Indentation tests were conducted by pushing flat, vertical indentors of two different widths (50 and 100 mm) against the edges of floating, freshwater ice at different velocities (0.6-150...
Analysis and Design of Structures with Outrigger Arms
Although sophisticated computer methods are available for analyzing an entire building structure, there is a need for simplified methods (a) for checking the accuracy of the computer analyses,...
