Title:
Shape optimization of shells and locking 
Abstract:
In the present paper, the significance of a reliable finite element formulationin the optimization process is discussed. First, analytical sensitivitiesfor a shell element based on the DSG concept are derived. Due to its simplicity,efficiency and the possibility to compute sensitivities analytically, theDSG method turns out to be perfectly well-suited for shape optimization.The effects of locking on shape optimization of shells are studied by numericalexperiments using a standard displacement sh...    »
