Simulation creep phenomenon of a steel pipe in Abaqus

In this tutorial Simulation creep phenomenon of a steel pipe in Abaqus has been investigated. Creep is a time-dependent deformation of a material while under an applied load that is below its yield strength. It is most often occurs at elevated temperature, but some materials creep at room temperature. Creep terminates in rupture if steps are not taken to bring to a halt. Creep data for general design use are usually obtained under conditions of constant uniaxial loading and constant temperature. Results of tests are usually plotted as strain versus time up to rupture. As indicated in the image, creep often takes place in three stages.  In the initial stage, strain occurs at a relatively rapid rate but the rate gradually decreases until it becomes approximately constant during the second stage. This constant creep rate is called the minimum creep rate or steady-state creep rate since it is the slowest creep rate during the test. In the third stage, the strain rate increases until failure occurs.  Creep in service is usually affected by changing conditions of loading and temperature and the number of possible stress-temperature-time combinations is infinite.  While most materials are subject to creep, the creep mechanisms is often different between metals, plastics, rubber, concrete

In this tutorial the steel pipe with branch is modeled as three dimensional part which you can see it on the below figure 

The elastic and creep plasticity has been implied for the material.For this analysis to steps as static and visco has been used.The symmetry boundary and internal pressure as load have been applied to the pipe. Many partition are used to create proper mesh as above figure. After the simulation the creep strain and creep plastic strain are achievable. You can see some figures of the results at below
