Finite Element Method

Applications are invited from highly motivated researchers for two postdoctoral positions immediately available in the Multiscale Multiphysics Design Optimisation (M2DO) lab, led by H Alicia Kim.

Candidates must have a strong background in mathematical optimization, finite element method and computer programming, and be committed to applying rigorous mathematical tools to structural design and optimization. Experience or interest in developing numerical methods and/or large-scale high performance computing and collaborative software development is also desirable.

Imitating origami principles in active or programmable materials opens the door for development
of origami-inspired self-folding structures for not only aesthetic but also functional purposes. A
variety of programmable materials enabled self-folding structures have been demonstrated across
various fields and scales. These folding structures have finite thickness and the mechanical
properties of the active materials dictate the folding process. Yet formalizing the use of origami
rules for use in computer modeling has been challenging, owing to the zero-thickness theory and

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.

A recently published paper  "Evaluating the macroscopic yield behaviour of trabecular bone using a nonlinear homogenisation approach" links the micromechanics of bone to its macroscopic behaviour. The paper may be of interest to colleagues on this forum. The abstract is provided below.

I am currently looking to fill an open PhD position in a project titled:

Advanced Virtual Design of 3D Printed Fusion Reactor Components

This is to continue recent work that uses X-ray tomography, high performance computing and finite element analysis to design the plasma facing wall of the ITER reactor. Recent related publications can be found below:

Applications are invited for a fully funded PhD studentship at the University of Manchester to help develop the next generation of simulation tools. These will be used to evaluate the structural integrity of novel aerospace composites under a wide range of operational conditions. The student will join a €3-4M euro research project that has recently been funded to investigate the use of biomaterials in aerospace composites. The project involves a range of academic and industrial partners in Europe and China, providing many opportunities for overseas research visits.

This paper presents an effective numerical approach for welding process
parameter optimization to minimize weld-induced distortion in
structures. A numerical optimization framework based on coupled Genetic
Algorithm (GA) and Finite Element Analysis (FEA) is developed and
implemented for a low and a high fidelity model. Classical weakly
coupled thermo-mechanical analysis with thermo-elasto-plastic
assumptions is carried out for distortion prediction of numerical
models. The search for optimum process parameters is executed by direct
integration of numerical models and GA-based optimization technique. The
developed framework automatically inserts the process parameters into
the simulation models, executes the FE-based welding simulations and
