Problem with coefficient of thermal expansion in ADINA

Problem with coefficient of thermal expansion in ADINA

Problem with coefficient of thermal expansion in ADINA

(OP)
Hi,

Is there anyone using ADINA? Please help me.

I'm using ADINA to model an integral abutment bridge. I want to use a coefficient of thermal expansion for an elastic isotropic and orthotropic material (steel, concrete, asphalt).
I have the 7 materials, and a table of their properties changing with temperature. Whenever I put the coefficient into material properties, the program required a temperature file. I don’t know which the format of the temperature file is. Because I have 7 materials so I will also have 7 files of properties vs. temperature. I try with one temperature file and the program reported an error.

I try to search for help in online help and program help, but no use.

Please help me

RE: Problem with coefficient of thermal expansion in ADINA

I have done models of integral abutments using ADINA and had no problems.

If you want to alter properties with temperature I think you need to use thermo isotropic material, not elastic isotropic material etc. Each material is defined separately with a different material number and the material definition includes a table of properties varying with temperature.

hi,

I also tried like you, but Adina require a temperature file to process. I have 7 files , and actually i don't know about the format of the file.

RE: Problem with coefficient of thermal expansion in ADINA

You need to apply a temperature load to all the geometric entities that have material properties varying with temperature. (Model>loading>apply load>load type>temperature).

The error message is only a warning and says it assumes zero temparture by default if no value is set.
