Causes Of Failure

The paper presents an example of failure of the foundation slab of a complex of multi-storey buildings and an analysis of the complex reasons of its origin. In addition, the method and technology of the repair was presented in conditions of continuous, though limited operation of the facility, taking into account the existing limitations. The repair involved the necessity of performing specialized preparatory works, proper assembly and protection of the designed strengthening.

Comparison Of Results

For decades attention has been paid to interaction of foundation structures and subsoil and development of interaction models. Currently there are several software that, can deal with the interaction of foundations and subsoil. The purpose of this paper is to compare resulting deformation of the slab, subsidence of the subsoil, bending moments and contact stress calculated by two different software based on FEM calculations. Calculated deformation of the slab is compared with deformation measured during experiment.

Causes Of Failure

AbstractForty cases of failed combined approach tympanoplasty were analysed. The commonest cause of failure was adhesions between the facial ridge and the tympanic membrane, causing segmental attico-mastoid malaeration in 51.3 per cent of cases followed-up continually. Other causes were, large dermoids, incomplete removal of squamous epithelium, and eustachian tube obstruction. Eustachian tube dysfunction did not appear to be a major cause of failure.

Causes Of Failure

Aluminum is a metal matrix material which is widely used in different industrial as well as engineering applications.it has a great advantage due to its remarkable properties like less density, formability, and light in weight, recyclability and other properties. but, failure of aluminum matrix materials are the main problems in aluminum industries now a days.in this review role of aluminum and its alloys as matrix materials, their failure modes, causes of failure and optimization techniques to minimize this failure modes and causes of failure are discussed. Sources are reviewed which are from 2005 to recent one. Consequently, most modes of failure, causes of failure and most optimization techniques of aluminum and its alloy matrix materials are found. most modes of failure are mechanical related like fatigue failure, surface cracking, ductile failure, porosity formation, and stress related like stress corrosion cracking, surface weakness due to repeated stresses and other factors are summarized.in causes of failure mostly like corrosion formation, wear formation and poor mechanical properties are discussed.
