This article comprises three main parts. The ﬁrst describes the manufacturing process of Core-Y. The second develops an experimental study of the material based on quasi-static axial compression test on cylindrical specimens of Core-Y. The results of the experimental tests are presented and analysed and the essential mechanical properties are determined. The third part presents a study of constitutive and numerical modelling, based on the experimental results. The main objective of this numerical study is to analyse the energy absorption capacity of metallic tubular structures incorporating Core-Y, aiming to study new applications for this composite material. A numerical model to simulate the tubular structures tested experimentally is developed, implemented and validated, using the ﬁnite element analysis software Abaqus. The overall results anticipate interesting expectations in terms of lightweight cork based composite materials and systems.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Rosa, M E</style></author><author><style face="normal" font="default" size="100%">Pereira, H</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE EFFECT OF LONG-TERM TREATMENT AT 100-DEGREES-C-150-DEGREES-C ON STRUCTURE, CHEMICAL-COMPOSITION AND COMPRESSION BEHAVIOR OF CORK</style></title><secondary-title><style face="normal" font="default" size="100%">HOLZFORSCHUNG</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">c</style></keyword><keyword><style  face="normal" font="default" size="100%">Cellular materials</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork</style></keyword><keyword><style  face="normal" font="default" size="100%">mechanical properties</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1994</style></year></dates><publisher><style face="normal" font="default" size="100%">WALTER DE GRUYTER &amp; CO</style></publisher><pub-location><style face="normal" font="default" size="100%">GENTHINER STRASSE 13, D-10785 BERLIN, GERMANY</style></pub-location><volume><style face="normal" font="default" size="100%">48</style></volume><pages><style face="normal" font="default" size="100%">226-232</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The effects of heating of cork in air at 100-degrees-C and 150-degrees-C&lt;br/&gt;for up to 42 days have been studied. Dimensional and mass changes&lt;br/&gt;induced by heat treatment were measured and the chemical composition was&lt;br/&gt;analysed. The thermal degradation of cork is small for short periods of&lt;br/&gt;treatment but increases with time and temperature. Cork looses after 42&lt;br/&gt;days of treatment 6.8 % of its mass at 100-degrees-C and 19.9 % at&lt;br/&gt;150-degrees-C. Cork extractives and polysaccharides were found to be the&lt;br/&gt;most temperature labile components. The cellular structure, observed by&lt;br/&gt;scanning electron microscopy, did not change with treatment in these&lt;br/&gt;conditions. Compression curves of untreated and heat treated cork&lt;br/&gt;samples were obtained, which show an increase of compression strength&lt;br/&gt;upon heating for short exposure periods and a decrease for longer ones.&lt;br/&gt;The changes observed in the compression behaviour of cork treated at&lt;br/&gt;100-degrees-C and 150-degrees-C were related to the chemical composition&lt;br/&gt;changes induced by heat treatment.</style></abstract></record></records></xml>
