    Damage model for hardening and softening material in general state of stress (1994)
    Springer
    Acta mechanica solida Sinica 7 (1994), S. 323-333 
    Details
    ISSN: 0894-9166
    Keywords: softening ; damage ; multiaxial ; constitutive model
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Abstract The present paper is aimed to simulate progression of damage, hardening and softening response in brittle materials such as concrete or rock in general state of stress. Similar shape of surfaces for yield, failure and damage progressing are available, and softening strain is treated as plasticity. Then, the proposed model is applied to solving several boundary value problems.

    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
    Keywords: Structural optimization ; engineering design ; optimality conditions ; calculus of variations ; structural mechanics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: 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
    Keywords: Structural optimization ; engineering design ; optimality conditions ; calculus of variations ; structural mechanics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: 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
    Keywords: optimal design ; non-linear analysis ; critical states ; large displacements ; imperfections ; truss and beam structures ; Engineering ; Numerical Methods and Modeling
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Mathematics , Technology
    Notes: 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.
