New method for accurate and consistent identification of modal parameters
收藏 引用
JOURNAL OF GUIDANCE CONTROL AND DYNAMICS 1996年 第5期19卷 992-999页
作者: Lin, RM Ling, SF Nanyang Technological University Singapore 2263 Singapore
A new method for the estimation of modal parameters is presented. Unlike the majority of existing methods, which involve complicated curvefitting and interpolative procedures, the proposed method calculates the modal ... 详细信息

A FAST DOT-PRODUCT ALGORITHM WITH MINIMAL ROUNDING ERRORS
收藏 引用
COMPUTING 1994年 第4期52卷 355-369页
作者: KOBBELT, L 1. Institut für Betriebs-und Dialogsysteme Abteilung geometrische Datenverarbeitung Universit?t Karlsruhe D-76128 Karlsruhe Federal Republic of Germany
We present a new algorithm which computes dot-products of arbitrary length with minimal rounding errors, independent of the number of addends. The algorithm has an O(n) time and O(1) memory complexity and does not nee... 详细信息

Micromechanical modeling of coupled viscoelastic-viscoplastic composites based on an incrementally affine formulation
收藏 引用
INTERNATIONAL JOURNAL OF SOLIDS AND STRUCTURES 2013年 第10期50卷 1755-1769页
作者: Miled, B. Doghri, I. Brassart, L. Delannay, L. Catholic Univ Louvain IMMC B-1348 Louvain Belgium
This study proposes a micromechanical modeling of inclusion-reinforced viscoelastic-viscoplastic composites, based on mean-field approaches. For this, we have generalized the so-called incrementally affine linearizati... 详细信息
