Optimized upper bound analysis of polymer coated metal rod extrusion through conical die
… process. In the present research study a new upper bound analytical model is developed to predict the forces required to conduct extrusion of a polymer coated metal rod successfully. The search for the lower upper bound power functional is modeled as a non linear optimization problem. …

Shear strength of reinforced concrete wall-beam structures: upper- bound analysis and experiments
This study presents rigid-plastic methods of analysis of shear failure in reinforced concrete (R. C.) wall-beam type structures when subjected to in-plane loading. The upper-bound approach is emphasised. Present shear design practice (e.g. BS8110:1985) relies much upon empirical solutions, but it …

An investigation into the punching shear failure in R.C. waffle slabs subjected to concentrated load
… study was carried out in parallel; the Upper Bound Analysis and Nonlinear Finite Element Analysis were employed to predict the ultimate punching load and also to serve the purpose of investigating the failure mechanism. Alternative methods, modified from the methods recommended by the …

Behaviour of continuously supported self-compacting concrete deep beams
… equations of the effectiveness factor used in upper-bound analysis can reasonably be applied to the prediction of the load capacity of continuously supported SCC deep beams although they were proposed for normal concrete (NC). The proposed three dimensional FE model accurately predicted the …

Fundamental and engineering application studies of pressure-assisted injection forging of thick-walled tubular components
… modelling to simulate the forming processes. An upper bound analysis of Pressure-assisted injection forging of thick-walled tubular components with hollow flanges was conducted and formulated solution for the forming process was developed, by which the maximum forming-force for a given component …

Behaviour of continuous concrete deep beams reinforced with GFRP bars
… to be used with the STM. Additionally, an upper bound analysis was developed to predict the load capacities of the tested specimens considering a reduced bond strength of GFRP bars after assessing the old version recommended for steel RC continuous deep beams. A good agreement between the …
