Hello,<\/p>\n
I am trying to model physical processes in which different kinds of material expansions can occur:<\/p>\n
-thermal expansion (due to a rise in temperature)<\/p>\n
-swelling due to water uptake<\/p>\n
-expansion because of ice formation in the porous structures of the material<\/p>\n
All these expansions are very similar in their mathematical description on a macroscopic level; they are isotropic and depent linearly on a parameter (temperature, water content, ice content). However, the only way I know to realize this in mechanical is by the (mis-)use of the isotropic coefficient of thermal expansion. This includes taking my input data (temperature, water content etc.), multiplying by the respective expansion coefficient and summing it up to get a “substitute”-temperature, which can be used in the mechanical simulation (setting the expansion coefficient in ANSYS to 1). I was wondering whether there is a smarter way to do this, since it is quite labor intensive and does not seem to be the way the programm was intended to be used.<\/p>\n
I should stress that the input data (temperature, water content etc.) does not result from another ANSYS simulation, it is something I want to feed directly into mechanical.<\/p>\n
Thanks a lot in advance!<\/p>\n","protected":false},"template":"","class_list":["post-371284","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
