Two-Dimensional Joint Analysis Under Shear Loading Using Enriched Finite Element

This paper compares finite element predictions of strain and strain range for short flat bars with projections and values estimated using simple notch stress-strain conversion (NSSC) rules. Results of six geometries, associated with local and remote restraints and under both axial and shear loading conditions, are presented. Also, some previously published experimental and numerical results for other two-dimensional problems are compared with NSSC rule estimates and the findings discussed in association with the findings from the current work. The comparison has indicated that the choice of the most suitable NSSC rule is both geometry and load dependent. It is suggested that the intermediate rule with an m value of ∼ 0.6 may be more appropriate under extreme conditions of large stress concentration factor (generally associated with local restraints or loading) and high load.

ABSTRACT: This work presents the dynamic response of a lock subjected to the horizontal S0E component of the El Centro earthquake for empty and completely filled water chamber cases, by coupled fluid-structure analysis. Initially, the lock was studied by approximation, considering it similar to the case of a double piston coupled to a two-dimensional acoustic cavity (tank), representing a simplified analytical model of the fluid-structure problem. This analytical formulation can be compared with numerical results, in order to qualify the responses of the ultimate problem to be investigated. In all the analyses performed, modeling and numerical simulations were done using the finite element method (FEM), supported by the commercial software ANSYS.

Abstract Development of the banded radial tire is discussed. A major contribution of this tire design is a reliable run-flat capability over distances exceeding 160 km (100 mi). Experimental tire designs and materials are considered; a brief theoretical discussion of the mechanics of operation is given based on initial two-dimensional studies and later on more complete finite element modeling. Results of laboratory tests for cornering, rolling resistance, and braking are presented. Low rolling resistance, good cornering and braking properties, and low tread wear rate along with good puncture resistance are among the advantages of the banded radial tire designs.
