1. Pipeline Stress Analysis Through Stress Function Fittings
Abstract This work presents a hybrid experimental technique for stress analysis in pipes due to soil-pipe interaction. It was used a variation of Digital Speckle Pattern Interferometry (DSPI) combined with a small indentation setup for acquiring radial displacement points. Data collected are fitted under the Airy stress functions method for the determination

2. DYNAMIC BEHAVIOR OF BURIED PIPES: METHODOLOGY AND COMPUTATIONAL IMPLEMENTATION / COMPORTAMENTO DINÂMICO DE DUTOS ENTERRADOS: METODOLOGIA E IMPLEMENTAÇÃO COMPUTACIONAL
This work presents a numerical methodology for the analysis of buried pipes employed by the transport of oil and gas subject to dynamic loads. Emphasis is given to seismic loads. A finite element model based on a special class of beam element for the pipe representation is employed. Both geometric and material nonlinearities are considered in a total Lagrang

3. A NUMERICAL MODEL FOR THE ANALYSIS OF BURRIED PIPES / MODELO NUMÉRICO PARA O ESTUDO DO COMPORTAMENTO DE DUTOS ENTERRADOS
This work presents a numerical methodology for the analysis of buried pipes employed by the transport of oil and gas. Both geometric and material nonlinearities are considered in a total Lagrangean formulation. A special type of beam element is employed in the finite element discretization. The equilibrium equations are formulated based on the virtual work p
