Relating material processing to microstructural details is well studied, and relating toughness to structural safety is standardized. However, more development is needed to relate microstructural details to toughness. By providing a bridge between complex, multi-parameter microstructural geometry and properties to macroscopically observable fracture toughness, this research will deliver a functional tool to understand and analyse the material in a new way from material manufacturing process to the safety of the whole structure.
The 3mE Faculty trains committed engineering students, PhD candidates and post-doctoral researchers in groundbreaking scientific research in the fields of mechanical, maritime and materials engineering. 3mE is the epitome of a dynamic, innovative faculty, with a European scope that contributes demonstrable economic and social benefits.
The Department of Materials Science and Engineering (MSE) of Delft University of Technology undertakes coherent and innovative research dedicated to developing, producing, characterising, and manipulating materials, with a focus on metals. The aim is to develop fundamental understanding, forming the basis for better performance and a longer life cycle with preservation of functionality, while at the same time optimising sustainable use of resources and minimising the environmental footprint.
The Mechanical Behaviour group focuses on identifying fundamental mechanisms of fracture in complex multiphase materials. The aim is to understand damage evolution as well as failure initiation and to gain insight into the relation of microstructure to performance and reliability of modern materials and components made from them. The research of the group follows both experimental and numerical approaches to obtain a better physically-based understanding of the failure phenomena encountered.

The MicroTough project aims at developing a relation between microstructural characteristics of high-strength steels and their fracture toughness. We will generate a physically-based statistical model to predict cleavage fracture based on a statistical distribution of microstructural parameters. By providing a bridge between complex, multi-parameter microstructural geometry and properties to macroscopically observable fracture toughness, this research will deliver a functional tool to understand and analyse the material in a new way from the material manufacturing process to the safety of the whole structure.
The project is organised along two interrelated sub-projects, which means a close collaboration between 2 PhD students will be expected. In project 1, high-strength steels with appropriate chemical composition will be generated and subjected to characterisation of 3D microstructure, microstructural mechanical properties, and cleavage fracture micromechanisms. Project 2 will focus on development and validation of the fracture model, considering the statistical distribution of microstructural properties. This is a joint project between the TU Delft and TNO, with Allseas Engineering, the Dutch Ministry of Defence, Dillinger, and Lloyds Register. The responsible department at TNO will be Structural Dynamics, which brings structural research into application in the Dutch and European maritime and offshore industry.
