Equilibrium analysis of masonry domes
… limit state conditions and the principles of the lower bound theorem, the modified thrust line method was used to ascertain the theoretical minimum thrust of spherical and pointed domes, a parameter that was previously unsolved. Several methods to estimate minimum thrust to-weight ratio were …

Lower-bound shakedown analysis of pavements by using the interior point method
… in particular by rolling contact. Based on the lower-bound theorem by Melan, the shakedown load for pavements under cyclic rolling contact loading can be determined. The thesis is composed of three main parts. First, a method for the shakedown analysis of repeated sliding/rolling line contact as …

The Collier Memorial : a study of theory and construction
… the most critical phase of construction-the lowering of the vault. This was accomplished by using a simple analytical approach to predict how loads and deformations would evolve at every stage of the lowering process. Using the lower-bound theorem of plastic theory, thrust line analysis was …

Deterioration and Cracking in Reinforced Concrete Bridges
… component. Analytical predictions based on the lower bound theorem of plasticity were found to be overly conservative and did not capture the behaviour observed experimentally. This was attributed to a combination of local effects of greater anchorage capacity than predicted and global effects …

Anwendung direkter Methoden zur industriellen Berechnung von Grenzlasten mechanischer Komponenten
… independent of the number of loading cycles. The lower bound direct method leads to a problem of non-linear mathematical programming in con-junction with finite element methods. The considered problem is a convex non-linear optimisa-tion problem with constraints which necessitates for the …
