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.

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.
