Towards a unified design-by-analysis solution to pressure vessel nozzle-shell junctions under combined loading
… reinforcements, stress linearization, external loading cases, limit loads, and cyclic loads. In addition, elastic, elastic - perfectly plastic, full plastic and fracture analysis were performed.Stress intensity factors are obtained with the results of finite element analysis for various internal …

Study on structural integrity of welded components using the LMM
… response of welded components under cyclic loading conditions and developing methods to predict their safe life is of significant importance. The work within this thesis focuses on the investigation of cyclic plasticity and creep-cyclic plasticity interaction of welded components, and the …

Biomechanical Testing of Two-Level Cervical Disc Arthroplasty
… lateral bending, and axial rotation to an end-limit load of 3-Nm or 45o rotation. Rotations at the superior, implanted, and inferior motion segment units (MSU) of the instrumented conditions were normalized to the non-instrumented condition and analyzed using one-way ANOVA and …

Limit and shakedown analysis of structures by the finite element method
Limit and shakedown analyses are powerful methods in designing pressure vessel components and other engineering structures. With the development of computer technology the use of finite element analysis as an alternative tool for engineering structure design has become ever more increasing. In this …

Fracture mechanics analysis of offshore wind turbine monopile structures for lifetime extension
… defects from the time of fabrication or due to loading. Therefore, later life fatigue calculation must focus on the crack propagation phase. Crack propagation is analysed using fracture mechanics. It requires the calculation of stress intensity factor (SIF) which is a function of structure …

Anwendung direkter Methoden zur industriellen Berechnung von Grenzlasten mechanischer Komponenten
… operating safety-critical structures under heavy loading conditions. Many of these structures or structural components behave ductily and undergo plas-tic deformations under severe loading or under some normal operating conditions. Their life-time may be determined by fatigue failure or …
