چکیده
One of the priority areas theoretical research in field building structures is to reduce their own weight at a given resource - rationalization. There certain number which form and nature external load are interdependent. The most striking representative that perceive lateral pressure from bulk material retaining walls. From above review modern scientific aimed finding rational parameters walls, it follows authors, as rule, describe cantilever wall by finite reduction its or cost structure was taken target function. In this case, on does not change. idea underlying work soil backfill, holds it, considered single system. system, configuration determines magnitude distribution. sequence actions solve problem searching for leads division curved foam into linear sections. anchor support represented an additional concentrated force applied fixing point. dependences between attributes stress-strain state system angles inclination sections constructed. wall, will minimize potential deformation energy found within framework BEA method. Using numerical output data, validity proposed method demonstrated. realization calculations reduced search extremum objective function n variables where acts functionb combination system's breakdown variables. solution implemented conjugate gradient result calculations, image obtained minimizes introduced criterion.

The Effect of Normal Anisotropy on Thin-Walled Tube Bending
Thin-walled tube bending has common applications in the automobile and aerospace industries. The rotary-draw-bending method is a complex physical process with multi-factor interactive effects and is one of the advanced tube forming processes with high efficiency, high forming precision, low consumption and good flexibility for bending angle changes. However, it may cause a wrinkling phenomenon,...

Thin-Walled Tubes
The axial crushing of thin-walled tubes has been the subject of extensive research in the past. The existing kinematic models for predicting crushing behavior of axially loaded thin-walled tubes are systematically reviewed and analyzed. The advantages and limitations of each model are discussed. A new chain link model for circular tubes and square tubes is presented and studied in detail. Unlik...
متن کاملThin-Walled Structures
Experimentally determined natural frequencies and modes shapes are presented for an elastically point-supported isotropic plate with attached masses under impulsive loading. These results are compared to frequencies and to modes shapes determined from the Rayleigh–Ritz method and a finite element analysis using COMSOL. Accelerometers mounted at three locations on the plate, provide input for ME...

This paper presents a procedure to determine an element-length dependent strain and stress relation until fracture that is suitable for implementation in finite element models. This material relation is obtained experimentally with an optical measuring system. The strain until fracture is calculated from the measured surface displacements. The stress is derived from the measured force and the c...
