One of the current challenges in the domain of the multiobjective shape optimization is to reduce the calculation time required by conventional methods. The high computational cost is due to the high number of simulation or function calls required by these methods. Recently, several studies have been led to overcome this problem by integratinga...

In recent years, the automotive industry has known a remarkable development in order to satisfy the customer requirements. In this paper, we will study one of the components of the automotive which is the twist beam. The study is focused on the multicriteria design of the automotive twist beam undergoing linear elastic deformation (Hooke's...

In this paper, we study a multicriteria shape design of a highly nonlinear mechanical 2D structure, namely the shape optimization of the aerosol can bottom. In fact, it is made depending on two criteria, the dome growth DG and the dome reversal pressure DRP, that define the resistance of the bottom against the internal pressure. This two...

Aerosol cans are usually made of thin high performance steel and are fi lled with fluid at high pressure. For these two reasons, and considering usage and packaging requirements, the structural stability of their ends, top and bottom is then delicate to maintain. In the present work, we address the problem of shape optimization of the bottom of...

Lors de la fabrication de tôe par laminage, des défauts périodiques peuvent être marqués par les cylindres qui compressent le métal. Un contrôle automatique est incorporé dans le processus afin de détecter les défauts par traitement numérique des images prises par des capteurs. Ces images sont de grandes tailles et fortement bruitées de sorte...

In recent years, the signiﱂcant increase in number of connections to photo- voltaic installations in the public networks has caused greater risks. Meth- ods involving in detecting situations such as islanding, damage on the trans- port network, and normal situations without special event arise have been exploited, however, each method has its...
