Book 1988f structural optimization under stability constraints occurred only in the last twenty years. In numerous optimal structural design problems the stability phenomenon becomes one of the most important factors, particularly for slender and thin-walled elements of aerospace structures, ships, precision

Elements of the Theory of Structural Stability,. The fundamental motion is then described by static displacements constant in time and zero velocities, corresponding to equilibrium. In creep problems, stability of a quasi-static motion may also be investigated.

Problems of Optimal Structural Design,ain constraints. These constraints are usually expressed in terms of some other variables, called state variables or behavioural variables; they may also appear in the objective function and are interrelated and related to design variables by the equations of state.

Thin-Walled Bars,al buckling of plate or shell elements of thin-walled bars, lateral buckling of individual elements and various possible combinations. Overall buckling modes are more typical for bars with open profiles and local buckling modes — for closed profiles, but this is not a general rule.
