A model problem for a weight optimization

S. Lejla & L. Angermann
A weight-optimization method for the uniaxial bar under compressive force and self-weight is proposed. The first (initial) step is the shape-finding analysis under the assumption of a uniform stress distribution along the height of the bar. The second step is the weight optimization, i.e. the determination of minimum cross section for the given initial shape, load and material. The weight of the bar is taken as the objective function, the maximum stress in the bar...
