in this work, an inverse finite element formulation was modified for considering material anisotropy in obtaining blank shape and forming severity of deep drawn orthotropic parts. in this procedure, geometry of final part and thickness of initial blank sheet were known. after applying ideal forming formulations between material points of initial blank and final shape, an equation system was obt...

ILE (Interactive Learning Environment) is a highly multidisciplinary research domain. Design of such systems can not be done exclusively by computer scientists. Educational scientists, teachers who will prescribe the system and learners who will use it should also be involved in ILE design. Management of relationships between on the one hand computer scientists, and on the other hand other memb...

Today’s young people are surrounded by communication technologies that have a central place in their daily lives, such as the internet and mobile phones. Text messaging (short message service, SMS), for example, became a fully established phenomenon by the late 1990s. And teens were especially quick to adopt it. Today, SMS is the second most used mobile phone service (after voice) in Europe and...

This work presents a method (CDOM) for optimizing multiple system level assembly characteristics of complex mechanical assemblies by placement of their components. It addresses any component shape (including non-convex, hollow, sharp edges) connected together by functional constraints. This method finds multiple solutions to the Engineering Configuration Design Problem (ECDP) and proposes a sim...
