Abstract

Adaptive structures (structures equipped with controllable semictive dissipaters, so called structural fuses) with highest ability of adaptation to extremal overloading are discussed. The quasistatic formulation of this problem allows developing effective numerical tools necessary for farther considerations concerning dynamic problem of optimal design for the best structural crash-worthiness (see [2]). The structures with the highest impact absorption properties can be designed in this way. The proposed optimal design method combines sensitivity analysis with remodelling process, allowing approach (with material distribution as well as stress limits controlled) to an optimally redesigned structure. So called Virtual Distortion Method (see [1]), leading to analytical formulas for gradient calculations, has bee used in numerically efficient algorithm.
