For the past six years, we have been benefiting from the discovery by Tsai and Melo (2014) that the trace of the plane stress stiffness matrix ( tr ( Q ) ) of an orthotropic composite is a fundamental and powerful scaling property of laminated compos

Pure Plastic Behavior and the Assumption of Zero Elasticity at the Limit Load

Autor: Jeffrey T. Fong, Pedro V. Marcal, Robert Rainsberger

Publikováno v: Volume 2: Computer Technology and Bolted Joints.

The authors have introduced an analysis based on a modification of the Mooney Rivlin material to obtain an estimate of the plastic behavior of a structure near its failure point. In this paper we generalize the concept of zero elasticity and pure pla

Uncertainty Quantification of Finite Element Analysis of Uni-Axial Strength Test of Holed Composite Laminates

Autor: Robert Rainsberger, Jeffrey T. Fong, James J. Filliben, Pedro V. Marcal, Li Ma, N. Alan Heckert

Publikováno v: Volume 6B: Materials and Fabrication.

In the aerospace industry, open hole specimens of composite laminates have been used in standardized tests to generate design allowables. Using finite element method (FEM) based tool MicMac/FEA with AB AQUS code interface and statistical design of ex

Error Norm vs. Uncertainty Metric in Assessing Accuracy of the Finite Element Method

Autor: Pedro V. Marcal, Li Ma, Robert Rainsberger, Jeffrey T. Fong

Publikováno v: Volume 2: Computer Technology and Bolted Joints.

In most finite-element-analysis codes, accuracy is achieved through the use of the hexahedron hexa-20 elements (a node at each of the 8 corners and 12 edges of a brick element). Unfortunately, without an additional node in the center of each of the e
