   <dcterms:abstract>A l’actualitat, la utilització de materials compostos laminats està molt es-&#xd;
tesa a la indústria, especialment a l’aeronàutica, però també a la indústria&#xd;
de components d’aerogeneradors, d’embarcacions esportives i de l’automòbil.&#xd;
No obstant, els dissenys tı́pics no aprofiten al màxim totes les prestacions del&#xd;
material laminat, ja que es basen en solucions preexistents o solucions tipus&#xd;
que duen el material a un comportament molt semblant al comportament&#xd;
isòtrop. Per tant, és necessari plantejar nous dissenys de materials laminats&#xd;
que sı́ aprofitin l’anisotropia del material amb l’objectiu d’aconseguir ele-&#xd;
ments mecànics amb millors prestacions mecàniques com, per exemple, l’in-&#xd;
crement de la resistència, la reducció de la massa, l’increment de la freqüència&#xd;
fonamental de vibració o l’increment de les càrregues crı́tiques de vinclament.&#xd;
Una de les metodologies que permeten fer aquest disseny del material que&#xd;
es planteja és l’optimització de la seqüència de laminat del material, que&#xd;
determina com s’han d’apilar les diferents làmines que formen el materialquina ha de ser l’orientació de cadascuna. Per tant, aquesta tècnica permet&#xd;
trobar la solució òptima de com s’ha de construir el material laminat amb&#xd;
l’objectiu d’obtenir l’element mecànic que optimitza una o vàries propietats&#xd;
mecàniques</dcterms:abstract>
   <dcterms:abstract>Currently, the use of laminated composite materials is very&#xd;
industry, especially aeronautics, but also industry&#xd;
of wind turbine, sports boat and automobile components.&#xd;
However, typical designs do not take full advantage of all the features of the&#xd;
laminate material as they are based on pre-existing solutions or type solutions&#xd;
which lead the material to very similar behavior&#xd;
isotropic. Therefore, it is necessary to come up with new designs for laminate materials&#xd;
that the anisotropy of the material be taken advantage of in order to&#xd;
mechanical mechanisms with better mechanical performance, such as the&#xd;
increase in resistance, reduction of mass, increase of frequency&#xd;
fundamental vibration or the increase of critical bonding loads.&#xd;
One of the methodologies that allow to do this design of the material that&#xd;
it is proposed is the optimization of the laminate sequence of the material, which&#xd;
determines how the different sheets that make up the material machine should be stacked, the orientation of each one. Therefore, this technique allows&#xd;
find the optimal solution for how the laminated material should be constructed with&#xd;
the goal of obtaining the mechanical element that optimizes one or more properties&#xd;
