In this study a non-associated viscoplastic flow rule (NAVFR) with combining von Mises and Tresca loci in place of yield and plastic potential functions and vice verse is presented. With the aid of fully implicit time stepping scheme and discussing the other studies on plastic potential flow rules and also experimental results it is shown that the proposed NAVFR can be adopted to forecast the e...

The Cramér-von Mises family of goodness-of-fit statistics is a well-known group of statistics used to test fit to a continuous distribution. In this article we extend the family to provide tests for discrete distributions. The statistics examined are the analogues of those associated with the names of Cramér-von Mises, Watson and Anderson-Darling, called W , U and A respectively, and their comp...

B He who addresses fellow men, who wants to inform and convince them, who asks questions, can proceed in this way only because he can appeal to something common to all men—namely, the logical structure of human reason. ruce CaldwelPs recent writings on the Austrian school of economics (1982, chapter 6; 1984) are undoubtedly a positive contribution to economic thought. Caldwell argues correctly ...

OBJECTIVES To determine whether patterns of high internal tissue stress during gait are associated with patterns of monosodium urate crystal deposition and bone erosion in gout. METHODS We compared patterns of foot von Mises stress predicted computationally during gait in volunteers of normal and high body mass index (BMI) with patterns of urate deposition in gout and asymptomatic hyperuricae...

The aim of this animal study was to develop a model of orthodontic tooth movement using a microimplant as a TSAD in rodents. A finite element model of the TSAD in alveolar bone was built using μCT images of rat maxilla to determine the von Mises stresses and displacement in the alveolar bone surrounding the TSAD. For in vivo validation of the FE model, Sprague-Dawley rats (n = 25) were used and...

This paper presents the design of a deployable and foldable tsunami pod for older and disabled people who cannot run to higher grounds during a tsunami attack. In our design, we adopt an ellipsoid structure and use finite element method (FEM) to model the structure. Then, we conduct numerical simulation and confirm the safety based on the von Mises equivalent value and the Head Injury Criterion...

Nanoindentation is a useful technique for probing the mechanical properties of bone, and finite element (FE) modeling of the indentation allows inverse determination of elastoplastic constitutive properties. However, all but one FE study to date have assumed frictionless contact between indenter and bone. The aim of this study was to explore the effect of friction in simulations of bone nanoind...
