Modal Analysis of Complex Structures via a Sub-Structuring Approach [PDF]

International Journal of Advanced Design and Manufacturing Technology, 2021
In this paper, the problems arising from determining the modal properties of large and complex structures are investigated. For this purpose, the free interface component mode synthesis method has been used. In the following, Singular-Value Decomposition

An optimized tuned mass damper/harvester device [PDF]

, 2014
Much work has been conducted on vibration absorbers, such as tuned mass dampers (TMD), where significant energy is extracted from a structure. Traditionally, this energy is dissipated through the devices as heat.

Substructural Parametricity.

CoRR
Ordered, linear, and other substructural type systems allow us to expose deep properties of programs at the syntactic level of types. In this paper, we develop a family of unary logical relations that allow us to prove consequences of parametricity for a range of substructural type systems.

Strict lower bounds with separation of sources of error in non-overlapping domain decomposition methods [PDF]

, 2016
This article deals with the computation of guaranteed lower bounds of the error in the framework of finite element (FE) and domain decomposition (DD) methods.

Coupling of structures using frequency response functions

MATEC Web of Conferences, 2018
In the field of structural dynamics is common to predict the behaviour of a structure regarding structural modifications. In this context, the frequency based substructuring method is well-known to perform structural modifications based on the coupling ...

Numerical solution of two phase solidification problem using dynamic substructuring based on adaptive error estimation

Hittite Journal of Science and Engineering, 2015
N umerical solution of solidification of metals with a sharp front, in particular solidification of lead, is investigated. Considering the fact that the associated CPU time and memory requirement may be costly for large domains, alternatives are searched.

Microsatellite support for active inbreeding in a cichlid fish. [PDF]

PLoS ONE, 2011
In wild animal populations, the degree of inbreeding differs between species and within species between populations. Because mating with kin often results in inbreeding depression, observed inbreeding is usually regarded to be caused by limited ...

Risk-Weighted D-Optimal Sensor Placement for Substructure-Level Damage-Parameter Identification in Space Grid Structures Using Differentiable Flexibility-Submatrix Surrogates

Buildings
Optimal sensor placement (OSP) for structural health monitoring of large-scale space grid structures must enable reliable identification of localized member deterioration with sparse instrumentation.

Adaptive BDDC in Three Dimensions

, 2011
The adaptive BDDC method is extended to the selection of face constraints in three dimensions. A new implementation of the BDDC method is presented based on a global formulation without an explicit coarse problem, with massive parallelism provided by a ...
