The Stress-Strain Verification Test and Results Analysis of Riser Joint

Abstract

Based on experimental proof requirements, the stress-strain test is applied on riser joint after optimized design by method of the Finite Element to verify its correctness. Taking into account that the complex of selecting node in finite element can`t be met in experiment, 24 groups points in suspected area of the simulation results are collected. The results of the finite element simulation in the design are confirmed based on the analysis of the collecting data, except the local stress concentration and other issues.
