Application of thermomechanical biaxial stresses to a cruciform structure by iterative determination of the load components

Bosch, Alexander and Vormwald, Michael (2013):
Application of thermomechanical biaxial stresses to a cruciform structure by iterative determination of the load components.
In: ANSYS Conference & 31th CADFEM Users’ Meeting 2013, Rosengarten Mannheim, June 19-21, 2013, [Conference or Workshop Item]

Abstract

In cases where fatigue experiments must be supported by numerical calculations, the load components are undefined and just the strains at the gage locations are given. Only loads and constraints can be applied to a numerical model, but derived values like strains have to be determined iteratively. In the present paper a control algorithm is presented. The finite element software ANSYS Mechanical APDL 14.5 is used to apply given biaxial strains to a cruciform structure. An additional load component is the thermal load, which is also determined iteratively. The thermal calculation is divided into heating and cooling. The inductive heating is implemented by using an equivalent heat source, the compressed air cooling is modelled using an equivalent distributed convection cooling.
