A new joint industrial project, CaNeLis (Carbon-neutral lightweight ship structures using advanced design, production, and life-cycle services), has been launched, including three leading Finnish universities (Aalto University, Turku University, LUT) and several Finnish companies. Within the Business Finland NECOLEAP roadmap, the present project creates a leap to the future of climate-neutral ship structures, which can operate in the environment challenged by climate change in a safe, sustainable, and economically competitive way. The CaNeLis project aims significantly decrease the structural weight of the ship hull and shipbuilding's greenhouse gas emissions using carbon-neutral high-strength steel and novel structural solutions.
The Advanced Marine Structures research team at Marine Technology Group is now looking for individuals seeking a Master's thesis position at the CaNeLis project at Aalto University. Within the goal of the CaNeLis project, one main objective is to develop lightweight ship structures utilizing advanced manufacturing technologies and thinner and higher strength steels. You can address this objective by working on the following thesis topic.
Efficient process for FE modeling of stiffened panels with distortions from digital image correlation (DIC) measurements.
The impact of production-induced deformation on fatigue and buckling strength of thin and high-strength steel structures is needed to be analyzed. This topic aims to establish a versatile and efficient modeling routine to create FE models directly from DIC measurement data of deformation in stiffened panels.
Utilization of Equivalent Single Layer -shell element formulation in the non-linear analysis of distorted panels
The process to derive the non-linear membrane-, membrane-bending coupling, and bending stiffness of distorted stiffened panels is to be developed in commercial FE package(s) Abaqus/Ansys. The benefit of the approach is a significant reduction of modeling and computational resources leading to sustainable computational engineering of thin-walled structures.
Utilization of DIC in fatigue crack initiation and growth measurements
Understanding the fatigue crack initiation and growth behavior is needed to characterize fatigue damage in thin and high-strength steel structures. This topic studies the main affecting factors and develops a DIC measuring approach for high-precision measurements of welded components and structures.
Simplification of numerical modeling approach to applying strain-based crack growth method for high-performing welds
Further development of fatigue designs and quality control methods is required to utilize superior recent high-performing welds in structural design. This topic investigates the simplified and efficient FE models to apply the strain- based crack growth method for high-performing welds.
An ideal candidate is required to have a solid background and understanding of solid mechanics, material engineering, and/or marine structures. The candidate is expected to have sufficient skills in basic computation methods such as ABAQUS FEA, MATLAB, CAD, etc. S ufficient training in necessary skills to fulfill the thesis targets, e.g., technical numerical modeling or experimental skills and data analysis, will be provided by our research team.
Information about our research team
The Advanced Marine Technology research team has two professors (Heikki Remes and Jani Romanoff) supported by a staff scientist (Pauli Lehto), one post- doctoral researcher (Yuki Ono), and in total, six doctoral students, and one master student. Our research team has a holistic research environment covering different length scales important for developing sustainable lightweight ship structures, i.e., experimental, numerical, and theoretical methods from crystal scale to full-scale structures.
Salary and starting time
Aalto University follows the salary system of a Finnish university. The starting salary of a Master's thesis worker is 2224 €/month (gross). The preferred starting time is from January to June 2023.
