Defining material characteristics and applying gravity load
Defining material characteristics and applying gravity load
(OP)
Hey guys, I’m trying to do a model of a wall supported by a beam, with a distributed load on the top of the wall. Well, I need do define the following characteristics to my material:
Weight/Volume, Young’s Modulus, Poisson Ratio, Shear Modulus, Coefficient of Thermal Expansion, Concrete Compressive Strenght.
I find how to define the weight/volume (density), the Young’s Modulus and Poisson Ratio (elastic isotropic), but I don’t know how to define the other 3 characteristics. Do you have any tips to me?
I’m considering the self-weight of the elements, so I’m applying a gravity load. To apply this type of load I just need to put the acceleration of the gravity (g=9.81) on the component 2 field?
Warm Regards

RE: Defining material characteristics and applying gravity load
Actually, you don't need to define shear modulus. For linear isotropic elastic materials, only two elastic parameters is enough.
You can define your coefficient of thermal expansion in Mechanical -> Expansion.
For the other questions, it should be better to know what is the purpose of your analysis? What kind of model are your doing? 2D, 3D , axisymmetric?
