Worst Geometric Imperfections of Rods and Shells

2018
Various forms of geometric imperfections of compressed rods, which are subjected to loss of stability, have been considered in the normative literature. Similar investigations are also intensively carried out for the shells with imperfections, taking into account sub- and post-critical behavior of the systems, as well as an inelastic deformation of ...

Sensitivity of Crack Nucleation Parameters to the Geometric Imperfection

2008
In this experimental study, we compared the plane stress crack growth in identical specimens with and without a geometric imperfection. The initial imperfection is intended to trigger a progressive process of single-site necking followed by single-site cracking in a predefined location and direction.

Lateral Dynamics of a Moving Web With Geometrical Imperfection

Journal of Dynamic Systems, Measurement, and Control, 2001
In this paper, an analysis is provided for the steering of a long, warped web that is transported between two rollers. The web is modeled using the Timoshenko beam theory, which admits small amounts of elastic bending and transverse shearing. Closed-form solutions are obtained for three commonly encountered forms of in-plane imperfection: (1) a splice,

Sensitivity Analysis of Geometrical Imperfections in Aerospace Structures

SAE Technical Paper Series
<div class="section abstract"><div class="htmlview paragraph">Launch vehicle structures are designed to withstand flight loads while fulfilling their intended functional requirements. Most of these structures use cylindrical geometries and employ stiffened configurations—such as isogrid, orthogrid, or skin-stiffened designs—comprising ...

Sensitivity of Space Trusses to Member Geometric Imperfections

International Journal of Space Structures, 1995
The existence of some geometrically imperfect members in a space truss is almost inevitable, and the fact that they produce initial internal member forces is undeniable. This paper is not about how to avoid member imperfections, but rather is a step forward towards better understanding of the implications of having imperfect members. The paper attempts

INFLUENCE OF THE GEOMETRIC IMPERFECTIONS ON THE BUCKLING OF THIN PLATES

2014
Narin yapy elemanlary, eksenel yükler ve deprem yükleri altynda yerel ve global burkulmalara maruz kalyrlar. Bu nedenle sisteminin güvenli?i için elemanlaryn kontrol edilmesi gerekmektedir. Yapy elemanynyn bünyesinde bulunan geometrik kusurlar burkulma yükünü etkilemektedir ve bu tür elemanlar Euler burkulma yük seviyesine ula?mamaktadyrlar.
