The E² Bathe subspace iteration method
Since its development in 1971, the Bathe subspace iteration method has been widely-used to solve the generalized symmetric-definite eigenvalue problem. The method is particularly useful for solving large eigenvalue problems when only a few of the least dominant eigenpairs are sought. In reference …

On the predictive capability and stability of rubber material models
… Ogden model and the newly proposed Sussman-Bathe model, is investigated theoretically with continuum mechanics methods and tested numerically in various deformation situations using the finite element analysis software ADINA. In addition, a recently made available stability criterion of …

The enriched subspace iteration method and wave propagation dynamics with overlapping finite elements
… problem. The scheme is an extension of the Bathe subspace iteration method and a significant reduction in computational time is achieved. For the solution of wave propagation problems, the finite element method with direct time integration has been extensively employed. However, using the …

Contributions to the direct time integration in wave propagation analyses
… review an implicit time integration method, the Bathe method, that remains stable without the use of adjustable parameters when the commonly used trapezoidal rule results in unstable solutions. We then focus on additional important attributes of the scheme. We present dispersion properties of the …

An analysis of the TR-BDF2 integration scheme
… (PDEs). It was originally Professor KlausJiirgen Bathe who suggested that further analysis was needed in this area. We draw attention to numerical instabilities that arise due to insufficient numerical damping from the Crank-Nicolson method (which is based on the Trapezoidal rule) and demonstrate …

Four Pools | Four Qualities
… The bath house becomes place for patrons to bathe in the mineral baths in a meditative setting. This thesis investigates qualities of light and shadow, and how these elements activate the interior surfaces of form. The architecture is formed by the introduction of light and shadow in ways …

Texas Ranch
… provides well water for horses to drink and bathe in. A clear structural hierarchy exists in the buildings. I was interested in the relationship between the stacking of the walls and making a framework out of wood and steel. Details were resolved with special consideration for the materials …

A finite element method and the method of finite spheres enriched for analysis of wave propagations
… extension of the procedure introduced by Kohno, Bathe, and Wright for one dimensional problems. Specifically, the novelties are: two-dimensional problems are solved (and three-dimensional problems would be tackled similarly), a scheme is given to overcome ill-conditioning, the method is presented …

Towards optimal mixed finite elements for general shell structures
… Tensorial Components) shell elements proposed by Bathe, Dvorkin and Bucalem. The study demonstrates the superior performance of these elements. We also develop a new simple and effective triangular mixed-interpolated shell element and demonstrate the element reliability. Deriving the relation …

Analisi teorica, numerica e sperimentale dei processi di grandi deformazioni nei materiali duttili
… to "small deformation" case and introduce the Bathe-Montans plasticity model for the anisotropic solids. The Bathe-Montans model was implemented writing an UMAT subroutine for the FE code Abaqus Standard and numerically tested using different material and geometry/meshes. To validate the …

Are Nutrition and Food Security Concerns a Priority of Certified Nursing Assistants in Work and Family Environments?
… medical benefits through their employers. CNAs bathe, change, feed, and help toilet the residents of long-term care facilities. The stressful work and personal lives of CNAs leads to many problems such as high turnover rates, absenteeism, health problems, and elder abuse. In the United States, …

On triangular finite elements for general shell structures
… mathematical model (published by Chapelle and Bathe) from which most mathematical shell models are derived. Using the basic shell mathematical model in the formulation of shell elements provides insight that can be very valuable to improve finite element formulations.

A Very Small House: Designing for Good Living
… a refined place to cook, a refined place to bathe, a refined place to sleep. For the life of the inhabitant as a member of a family or a community: a refined place to gather and a refined place to extend. I use the word refined in this context to mean: very subtle, precise, or exact. A means …

An investigation into the efficacy of kinematics and kinetics method for stride-characteristic measurements of horses trotting on a treadmill
The aim of this study was to investigate the validity of stride characteristic measurements taken from the sternum by means of an Optical Motion Capture System (OMCS) and an Inertia Measurement Unit (IMU), in comparison with OMCS hoof markers. Measurements were taken from sound horses of a range of …

Solution methods for dynamic and non-linear finite element analysis
The computer analysis of structures and solids using finite element methods has now taken on very significant proportions. In many cases the safety of a structure may be significantly increased and its cost reduced if an appropriate finite element analysis can be and is performed. In the …

Inverse Monte Carlo simulation of biomolecular conformation and coarse-grained molecular modeling of chondroitin sulfate conformation, titration, and osmotic pressure
The first part of this thesis is concerned with the solution structure determination problem. Whereas many biomacromolecules, such as proteins, can be adequately characterized by a single conformation in solution, numerous other important molecules (e.g., nucleic acids, carbohydrates, and …
