    Optimal design of structures with unspecified loading distribution (1976)
    Springer
    Journal of optimization theory and applications 20 (1976), S. 359-380 
    Details
    ISSN: 1573-2878
    Schlagwort(e): Structural optimization ; engineering design ; optimality conditions ; calculus of variations ; structural mechanics

    Thema: Mathematik
    Notizen: Abstract The problem of the optimal distribution of loading on a structure that corresponds to the minimum of the elastic compliance or the maximum of the safety factor for plastic collapse is considered. Optimality criteria are derived, and their applicability is illustrated in the case of beams. Besides the optimally varying cross section, also the support positions and the load distribution are determined from the optimal solution.

    Optimal design of structures with variable support conditions (1975)
    Springer
    Journal of optimization theory and applications 15 (1975), S. 85-101 
    Details
    ISSN: 1573-2878
    Schlagwort(e): Structural optimization ; engineering design ; optimality conditions ; calculus of variations ; structural mechanics
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Mathematik
    Notizen: Abstract The conditions for optimal location of supports are derived for the case of elastic design for specified mean compliance and plastic design for given safety factor of plastic collapse. The optimal design problem is next formulated including position-dependent cost of support into the design procedure. Both rigid and flexible or yielding supports are considered.

    Sensitivity analysis and optimal design of non-linear structures (1998)
    Chichester [u.a.] : Wiley-Blackwell
    International Journal for Numerical Methods in Engineering 42 (1998), S. 1231-1262 
    Details
    ISSN: 0029-5981
    Schlagwort(e): optimal design ; non-linear analysis ; critical states ; large displacements ; imperfections ; truss and beam structures ; Engineering ; Numerical Methods and Modeling

    Thema: Mathematik , Technik allgemein
    Notizen: Sensitivity analysis for non-linear elastic structures in regular and critical states is first discussed including design parameters and initial imperfections. Next, the optimal design problem is formulated by considering imperfect structures and setting constraints on deflections and stresses. For structures with unstable post-critical response the limit load constraint is introduced in the optimization procedure. Several examples of truss optimization are provided. The level of initial imperfections can be regarded as design parameter and specified from the optimal solution. © 1998 John Wiley & Sons, Ltd.
