PhD position in numerical ice mechanics, Aalto University, Finland

We are looking for a doctoral student to work on numerical modeling of ridging of sea ice. Ridging is central to understanding the behavior of sea ice from scales varying from tens of meters up to hundreds of kilometers and has a close connection to sea ice dynamics models, which have an important role in predicting the effects of climate change. The applicant should be advanced in solid and computational mechanics and have at least average programming skills.

Postdoctoral Position at Oregon State University: Rock-Tool Interaction

I have an opening for a new postdoctoral scholar to join my research group, please see attached. The project is on the field-scale calibration of DEM models.

PhD studentship available at Kingston University London

A PhD studentship is available in the Department of Mechanical Engineering at Kingston University London.

The work will be dedicated to the discrete element modeling of pellets' compaction in orodispersible tablets.

The project is in close collaboration with the Kingston University's Department of Pharmacy and also the University of Strathclyde. The student will have access to the high-performance computing facilities and also to the relevant facilities to obtain experimental data for validation of the developed numerical models.

Doctoral Candidate Position in Computational Ice Mechanics

We are looking for a doctoral student to join our Arctic Marine and Ice Technology research group at the Aalto University (Finland), Department of Mechanical Engineering, to study ice-structure interaction process in shallow water using numerical simulations.  In the complex ice-structure interaction process an intact ice sheet fails into discrete ice blocks, which affect further stages of the process. Realistic calculations of ice loads due to this process require modeling of the ice blocks and their pile-up process.

Underwater Soil Mechanics Problem

I am an undergraduate student conducting a research project involving the design of a tool to aid astronauts to perform experiments on lunar surfaces and would like to request some direction about which analytical tools would be best suited for this application (i.e. FEA or DEM software/techniques). The specific scenario of interest is to design a tool that can act as an anchor in a sand-like medium (regolith) on the surface of the moon.

Post-doctoral positions at National University of Singapore (NUS) and Singapore University of Technology and Design (SUTD)

Starting April 2016, we will have openings for two post-doctoral fellow positions in experimental and computational mechanics of advanced polymers. These positions will support a new research program between Singapore University of Technology and Design (SUTD) and National University of Singapore (NUS) funded by Agency for Science, Technology and Research (A*STAR). The project focuses on synthesizing, characterizing, modeling, and simulating the thermo-mechanical behavior of polymers with covalent adaptable networks (CANs), e.g. vitrimers.

Impact Force plotting using Abaqus/Explicit

Hello Everyone

I am trying to simulate material dumping process from shovel onto mining dump truck. And for that i am using Abaqus/Explicit.  When i plot the contact force of material falling onto truck body under gravity, it gives me the maximum value of 0.12e+11, where as a simple theoretical analysis shows that the resulting impact force for 100 tons of material falling under gravity should be 9e5 N. I am not been able to understand the reason that why Abaqus /Explicit is exaggerating the impact/contact force so much. And i dont know how to correct this thing.

Shape of particles in DEM

Many granular materials encountered in engineering practice are of irregular shapes that are not essentially smooth or rounded. However, in DEM, grains are idealized as spheres and ellipsoids and their surface are assumed to be sufficiently smooth. As a result, I wonder why there is no model of  irregular shapes and what is the difficulty on implementing such a model? Is there any recent work aimed to simulate grains of irregular shape? Thanks a lot. 

the DEM's solutions for static mechanics seem strange

My own DEM(Discrete Element Method) program's solution for static problem seems strange.

I use my program to calculate the displacement of a cantilever under static pressure:

1. it seems my program shows convergence for static problem as the mesh gets denser. As the mesh grows denser(that means the particle becomes smaller), the displacement(of y direction)  of the free tip becomes smaller.
