Numerical investigation of unloading effects due to excavation of geometrically non-homogeneous stratified rock masses using finite element analysis (2018)
Presentation / Conference
Sauffisseau, R., & Ahangar Asr, A. (2018, June). Numerical investigation of unloading effects due to excavation of geometrically non-homogeneous stratified rock masses using finite element analysis. Presented at 6th European Conference on Computational Mechanics (ECCM 6) & 7th European Conference on Computational Fluid Dynamics (ECFD 7), Glasgow, UK

With the growth of population in the cities and the lack of land nearby, buildings are now reaching heights and depths (basements) demanding larger and deeper foundations. These excavations cause the unloading of the ground in some directions which c...

An evolutionary approach to modelling effects of chemicals on soils (2016)
Presentation / Conference
Ahangar Asr, A., & Javadi, A. (2016, March). An evolutionary approach to modelling effects of chemicals on soils. Presented at ACME-UK 24th Conference on Computational Mechanics, Cardiff

As part of a study undertaken to assess the impact of high-pH fluid circulation on the shear strength behaviour of a compacted soil with different additives and due to the complexity of the existing constitutive theories, a new approach was used, bas...

Air losses through the tunnel face in compressed air tunneling : a case study (2015)
Presentation / Conference
Ahangar Asr, A., & Javadi, A. (2015, September). Air losses through the tunnel face in compressed air tunneling : a case study. Presented at 16th European Conference on Soil Mechanics and Geotechnical Engineering, Edinburgh, UK

In this study field measurement data from Feldmoching tunnel in Munich were used to develop a model with the capability of predicting the air losses in compressed air tunnelling technique. In this tunnelling project, compressed air was used to contro... Read More about Air losses through the tunnel face in compressed air tunneling : a case study.

Conor (Eds.), Handbook of Genetic Programming Applications (483-499). Springer International Publishing. https://doi.org/10.1007/978-3-319-20883-1_19

In many cases, models based on certain laws of physics can be developed to describe the behaviour of physical systems. However, in case of more complex phenomena with less known or understood contributing parameters or variables the physics-based mod...
