STRENGTH PROPERTIES OF THIN-WALLED STRUCTURES DESIGNED WITH THE SADSF METHOD
Journal Title: Journal of Machine Construction and Maintenance - Year 2018, Vol 111, Issue 4
Abstract
This study presents general conclusions resulting from elastic FEM analyses of several dozen of thin-walled structures designed with the use of the application version of the method of statically admissible discontinuous stress fields (SADSF). The conclusions are illustrated with examples of two original structures designed to work under torsional load. The structures are based on I-sections, whose all surfaces are accessible from outside. Despite that fact, torsional rigidity of the structures is very high.Additionally, in these structures, we examined the effects caused by modifications consisting in local stiffening of some elements by applying edge stiffeners on their borders.
