I need to simulate a dual tire assembly traveling at a constant speed of 8.0 km/h and a nominal tire inflation pressure of 724 kPa on asphalt pavement structure using ABAQUS.
Can anyone help me with this?
First, the finite element model of tire structure is established. Because the tire structure is complex and composed of up to ten kinds of rubber and cord composites, this paper makes a reasonable simplification of the tire structure, and uses the software ABAQUS to establish the two-dimensional model of radial tire, and the foundation of the two-dimensional model The three-dimensional numerical model of tire structure is established by means of rotation and reflection.
Secondly, a large deformation nonlinear tire and rigid body contact model is established. Tire and deformable road surface contact simulation process, because both are deformable, there are difficult to calculate the convergence of the problem.
The stress field of the tire and the influencing factors of the interaction between the tire and the road surface are analysed.
Thank You for the reply sir...
I am new to abaqus, so I do not know much detail. I have to use amplitude and ramp loading concept. The loading area and amplitude has to be shifted. The tire footprint to be used is attached.
I am not able to do this.
I suggest you refer to significant work by Imad Al-qadi and his students/colleagues. For example:
Al-Qadi, I.L. and Wang, H. (2011). ‘Prediction of tire pavement contact stress and analysis of asphalt pavement response: a decoupled approach’, Proceedings Asphalt Pavement Technology, Tampa, Florida, USA, 27-30 March, Association of Asphalt Paving Technologists, pp. 289-315.

The following papers will help you to start with your work.
Yoo, P. J., et al. (2006). "Flexible pavement responses to different loading amplitudes considering layer interface condition and lateral shear forces." International Journal of Pavement Engineering 7(1): 73-86
Elseifi, M. A., et al. (2006). "Viscoelastic modeling and field validation of flexible pavements." Journal of Engineering Mechanics-ASCE 132(2): 172-178.

I suggest you have to familiarize with Abaqus so that you can be more specific with your problem. Your previous comment mentions the issue with the loading. Baek (2010) thesis will help you to resolve the issue. The ribs in the tyre are divided into different units which will be loaded separately at specific time interval as shown below.

Dear Dr Amjad, i think the propose reference by Nithin Sudersanan is highly recommended. Regards,
