Hi there,

I am trying to model a joint in asphalt pavement, is there a way to model it other than just using a friction factor?
Also, I am encountering an error related to the unconnected regions can anyone help me know how to find those regions?

Thanks in advance.

 

[FEA way]

Check how it’s done in literature (research papers). Frictional contact is likely the easiest way but maybe you could also use cohesive contact.

You can use unconnected_regions=yes when submitting the analysis or utilize eigenfrequency extraction to find unconnected regions.

Thanks for the info.

Hi,
here is my inp file for the indirect tensile strength test. But I am not sure why the forces are so I high and the deflection so less. I applied a loading rate of 50mm/min.

the density for the mater is in kg/m3
and youngs modulus in MPa.

Can you please take a look and let me know if there is something wrong or units not correct?

Thanks in advanse.
