Block-box structures load-bearing capacity under special loads

TOPOLOGY OPTIMIZATION OF STRUCTURES UNDER TRANSIENT LOADS

In this article, an efficient methodology is presented to optimize the topology of structural systems under transient loads. Equivalent static loads concept is used to deal with transient loads and to solve an alternate quasi-static optimization problem. The maximum strain energy of the structure under the transient load during the loading interval is used as objective function. The objective f...

5 Calculations for Structures under Mechanical Load – Examples of Geometrically Simple Structural Parts under Static Loads

The mechanical properties of polymeric materials, especially those of thermoplastics, depend to a much greater extent on temperature, time, and on the magnitude and nature of an applied load than those of metals. In addition, many environmental effects, such as UV radiation or exposure to certain chemicals, play a significant role in aging and related changes in properties. This can be difficul...

slope stability and bearing capacity of footings on top of slopes under repeated dynamic loads

although bearing capacity of footings on top of slopes under monotonic loadings have been investigated widely so far, safety and bearing capacity of these structures against repeated dynamic loads have not been considered well enough. in this paper, lower bound dynamic shakedown theorem in its numerical form has been employed to firstly obtain bearing capacity of strip footings on top of slopes...

On optimizing crash energy and load-bearing capacity in cellular structures

The energy absorption and load-bearing capacity under axial compression of some model cellular structures are studied with an eye toward optimization based on structural mass or volume available for deformation. Three configurations are considered: multilayer, multi-cell and multi-tube, all of a rectangular-cell topology. Loading is applied either parallel or normal to the cell axis. The cell’s...
