In the present work it is chosen to focus on the most common injection molding parameters/factors determining the quality of the mold geometry, i.e. uniform thickness, filling of the die and ejection of the molded item, i.e. extrusion. The mentioned injection mold parameters/factors are introduced in the topology optimization by defining a centerline of the initial domain and then penalize elements in respect to the distance to the defined centerline of the domain.</i><br /><a href="http://vbn.aau.dk/files/18560674/Implementation_of_Molding_Constraints_in_Topology_Optimization" rel="nofollow">Implementation of molding constraints in topology optimization</a>Joshua Stultshttps://www.blogger.com/profile/03506970399027046387noreply@blogger.com
