Hello, World! I'm Shreyas, a Research Assistant and a PhD candidate in the Institute of Geotechnical Engineering, headed by Univ. Prof. Dr.-Ing. habil. Christian Moormann at the University of Stuttgart.

I specialise in the field of large deformation modelling and I am working on developing a novel numerical method called Material Point Method. The code was written from scratch in-house, can simulate solid, fluid and saturated components (think wet soil) and have implemented a library of constitutive laws, ranging from simple ones, like Mohr-Coulomb to complex laws that capture liquefaction, like UBCSAND. My interest lies is developing softwares for numerically modelling large deformations, for both solids and fluids.

I have a new website here. Check it out!

More about me

I had previously worked in Sundram Fasteners Limited in Chennai, India as an Assistant Manager in the Sales and Marketing department. I worked on with a team in getting a new manufacturing up and running, producing 8-Speed transmission components for General Motors and Panther Engine components for Ford Motor Company. I was also given the oppurtunity to take lead of a team, whose task was to ensure MMOG-A Level certification for the manufacturing plant.

I graduated with a M.Sc. in Computational Mechanics of Materials and Structures, and my Thesis dealt with implementing a novel contact algorithm combining classical finite elements and Material Point Continuum. I also presented my paper in Delft in 2017.

I started my PhD work examining ways to capture large deformation modelling as a consequence of liquefaction. My work published in 2019 examined the application of Material Point Method towards capturing the large deformations as a consequence of sea-dike failure due to liquefaction. I also applied this method towards simulating installation of an offshore-monopile. A comparison between the behaviour of different constitutive laws was also provided. I have worked extensively in FORTRAN, C++, Python and worked with commerical FE softwares like ABAQUS, PLAXIS and ANSYS.

Outside of work, I enjoy playing my Violin and my Flute. I also enjoy Distro-Hopping (favourite - Pop! OS, currently using - Arch (btw!)).

Experience

Research Assistant

University of Stuttgart
  • Currently working on a research project "VISSKA" supported by the Federal Ministry of Economic Affairs and energy, with the aim to develop a numerical forecast model for installing monopiles using the vibro piling method, and to numerically estimate the noise emissions.
  • Worked on a project funded by RWE AG to numerically simulate model piles. Developed a code using CPDI method and implemented a constitutive law to capture liquefaction effects during installation. Later, used the tool to compare the results against a pile installed on-site.
  • Developed a Fortran based Material Point Method tool with OpenMP parallelisation, capable of simulating large deformation in solid and fluid constituents.
  • Implemented a novel multibody contact algorithm, incorporating Finite Element domain into the Material Point continuum and used the numerical tool in third-party projects for RWE and Innogy SE.
  • Coordinator for the course Geoengineering and Geohydrology. Lectured and tutored the courses Engineering Materials, Numerical Modelling of Soils, Geoengineering and Geostatik.
February 2017 - Present

Assistant Manager
