RISAn Extended Karhunen-Loève Decomposition for Modal Identification of Inhomogeneous Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An extension of the Karhunen-Loève decomposition (KLD) specifically aimed at the evaluation of the natural modes of n-dimensional structures (n=1,2,3) having nonhomogeneous density is presented. ...
An Improved Numerical Calculation Technique for Large Elastic-Plastic Transient Deformations of Thin Shells: Part 1—Background and Theoretical Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent improvements are reported in both the theoretical formulation and in the finite-difference treatment of the relations governing the large-deflection elastic-plastic dynamic responses of thin ...
An Improved Numerical Calculation Technique for Large Elastic-Plastic Transient Deformations of Thin Shells: Part 2—Evaluation and Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based upon the theoretical formulation presented in Part 1 of this paper, improvements in accuracy and computational efficiency are realized. Comparisons of predictions with experimental transient ...
