About ROLICER

Fraunhofer Institute for Mechanics of Materials IWM

The main objective is to construct a knowledge-based system for advanced ceramic materials to bridge the gap in knowledge between the microstructural properties and degradation phenomena.

Fraunhofer IWM: Project Rolicer

Aims and Objectives

  • Quantification of the most relevant thermal, mechanical and tribological loads on the lifetime and degradation of the ceramic components under realistic loading conditions
  • Achieving a better understanding of the nature of chemical adhesion between ceramics and metals and studying the effects of stresses on the adhesion and natural flaw evolution in ceramic materials
  • Ensuring realistic lifetime predictions based on analyses which couple realistic loading conditions, microstructural information and degradation mechanisms
  • Designing structural polycrystalline ceramic materials with superior performance and enhanced functionality for future emerging and demanding applications

Approach

  • Modeling the damage nucleation, evolution and crack growth behavior in the ceramic materials based on realistic thermal and mechanical stress fields
  • Ensuring a »ceramic-friendly design« of the ceramic components, especially in rolling tools by reaching a design that minimizes critical thermomechanical and tribological stresses
  • Developing ceramic component prototypes and demonstrations that portray the materials functionality in real applications
  • Developing a comprehensive database addressing the most relevant degradation and damage mechanisms in order to reach optimal design and material combination resulting in fabricating components with improved lifetimes and products with superior quality

The Rolicer project is funded by FP7 under the call NMP.2010.2.5-1 - Nanosciences, Nanotechnologies, Materials and new Production Technologies with Grant agreement no: 263476.
