Development of a method for the characterisation of the compliance and stiffness matrices of uncoupled laminates
(1999)
The mechanical behaviour of composite materials is defined by three matrices of
stiffness/compliance : in-plane, flexure and coupling matrix between in-plane and
flexure. The present work gives a method of test to ...
A phytochemical study of ilex and betula species
(1999)
A phytochemical study of the outer bark of native common holly (Ilex aquifolium), led to the isolation and identification of nine novel fatty acid esters of the pentacyclic triterpene a-amyrin. These compounds were the ...
Development of an expert system interface for the automated analysis of the sheet drawing metal forming process using finite element analysis techniques
(1999)
The objective of the work presented in this thesis was to develop an expert system for sheet
metal forming. In doing so an examination, of implicit and explicit Finite Element Analysis
(FE.A) codes and methodologies was ...
Determination of selenium in selenium enriched yeast.
(1999)
Selenium, although a rare mineral, is widely distributed in minute amounts in virtually all materials of the earth’s crust, its average abundance is approximately ~0.09ppm. Selenium is rarely found in its native state i.e. ...
