Finite element structural redesign by large admissible perturbations
(Elsevier, 1992)
In structural redesign, two structural states are involved: the baseline (known) state S1 with unacceptable performance, and the objective (unknown) state S2 with given performance specifications. The difference between ...
Catenary Mooring Lines with Nonlinear Drag and Touchdown
(University of Michigan, 1997-01-01)
Analytical expressions modeling the tension distribution and geometric deformation along catenary mooring line, including touchdown effect and nonlinear drag, are developed . The motions of a catenary mooring line in the ...
Stability Criteria for the Slow Motion Nonlinear Dynamics of Towing and Mooring Systems
(University of Michigan, 1996-11-01)
Analytical expressions for the necessary and sufficient conditions for stability of towing and mooring systems with several lines are derived based on the Routh stability criteria. These expressions are combined to provide ...
A Naval Architect's Guide to Practical Economics
(University of Michigan, 1991-10-01)
My purpose in writing this little book is to enable students of naval architecture to unravel the mysteries of ship design economics with little or no help from the academic staff. I was asked to provide such a guide, one ...
Survey for the Offshore Racing Council
(University of Michigan, 1994-05-01)
The Department of Naval Architecture & Marine Engineering at the University of Michigan has been assisting the Offshore Racing Council in gathering data to help improve the handicapping rules it administers. The results ...
Extension and Application of ZARNICK: A Nonlinear Simulation Program for High Speed Planing Hulls
(University of Michigan, 1997-05-01)
A nonlinear mathematical model (Zarnick, 1978) has been extended to calculate the motions of a variable deadrise planing boat in waves, using Zamick's low aspect ratio strip theory. It is assumed that the wavelengths are ...
Fully Nonlinear Ship-Wave Computations Using a Multipole Accelerated, Desingularized Method
(University of Michigan, 1997-04-01)
Chairperson: Robert F. Beck&&The inviscid ship-Wave problem with fully nonlinear boundary conditions is solved using a multipole accelerated, Desingularized Euler-Lagrange Time_domain Approach or DELTA method. The ...
In situ force-balance tensiometry
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-07)
Although a fundamental physical parameter, surface tension is difficult to measure. Common tensiometry inaccuracy comes from failure to control air–liquid–solid contact conditions, or account for liquid meniscus geometry ...
Invariant and consistent redundancy by large admissible perturbations
(Elsevier, 1992)
Structural perturbation theory has been developed over the past 16 years to relate two structural states modeled by the same Finite Element (FE) model but described by different values of the design variables. Relating an ...
Slow Motion Dynamics of Mooring Systems in Deep Water with Buoy Supported Catenary Lines
(University of Michigan, 1999-01-01)
The mathematical model for the horizontal plane slow motion dynamics of mooring systems with catenary chains supported by buoys is developed. Buoys are attached to a mooring line to help support part of the chain weight, ...
