dc.description.abstract In prezenta lucrare se apreciază pe baza modelării cu ajutorul metodei elementului finit coeficientul de reducere a rigidităţii pentru plăcile perforate subţiri în condiţiile limită de rezemare pe contur încastrare si simplă rezemare. Se prezintă dependenţe faţă de diferiţi parametri caracteristici. Soluţiile numerice obţinute se compară cu rezultatele experimentale proprii, cat si cu rezultate prezentate în diferite surse din literatură. en_US
dc.description.abstract The paper presents the numerical computation of the stiffness reduction coefficient for circular perforated plates in limit cases of boundary supporting: clamped and simply supported. The studied coefficient is presented in relation to different characteristic parameters of the plates. The FE results are compared to both experimental results obtained by the author and results presented in literature. en
dc.description.abstract Dans ce papier on apprécie, a l’aide d’analyse numérique d’éléments finis, le coefficient de réduction du rigidité pour les plaques perfores minces dans le cas de liaisons sur le contour – encastrement et appui simple. On pressente les relations entre certains paramètres. Les solutions numériques sont compares avec les résultats expérimentales propres et de même avec les résultats obtenus par de différent sources bibliographiques. fr
dc.description.abstract В работе излагается определение коэффициента ослабления пластины отверстиями для случая свободного опирания или защемления её контура. Приводятся зависимости от разных характерных параметров. Полученные результаты сравниваются с собственными экспериментальными данными, а также с данными излагаемыми в других работах. ru
