The Brittle Fracture Group, which has been a part of the Institute of Physics of Materials since its foundation, has been led from the beginning by doc. Ing. Miloslav Holzmann, CSc., who has investigated the transition region of brittle fracture of steels in detail using experimental fracture mechanics. The next group leader since 1990 was prof. Ing. Ivo Dlouhý, CSc., who expanded the research area of the group to include advanced ceramic and ceramic-based composite materials, which required a complete modernization of the experimental equipment to enable research at higher temperatures under lower loads.

The original focus of the group on the characterisation of the brittle fracture behaviour of iron alloys has now been significantly extended to the development, preparation, and subsequent evaluation of the properties of metallic, ceramic, and polymeric materials and their composites. The group uses theoretical principles, numerical simulations, experimental material preparation and advanced characterization to design new materials with desired properties. Understanding the fundamental physical mechanisms of deformation and failure under various loading conditions (tension, compression, bending and shear) at temperatures from -196 °C to 1500 °C is an integral part of the research, both for materials developed at the IPM and for materials from collaborating institutions or commercial entities. Targeted research for industrial partners is also an integral part of the group's activities.

Basic research areas of the group:

Design of new materials

  • Multicomponent materials (high entropy alloys, carbides, and borides, etc.)

  • Heterostructure (meta)materials

  • Multifunctional composites (especially based on ceramics)

Development of new materials

  • Preparation of metal and ceramic materials using mechanical alloying

  • Preparation of geopolymer composite materials

  • Preparation of nanostructured components, for example, graphene, by exfoliation technology

  • Preparation of materials by hydrothermal consolidation

Study of (micro)mechanisms and phenomena

  • Deformation and fracture phenomena in the structure under different loading conditions

  • Experimental and theoretical study of the initiation, growth, and interaction of twins

  • Material joints and their influence on deformation and fracture processes

  • Interface effects in composite materials

Experimental fracture mechanics

  • Static and dynamic fracture mechanical characteristics (fracture toughness, transit curve, J-da curve, etc.)

  • Transferability of fracture mechanics data obtained from small volume specimens

  • Fractographic analysis of fracture surfaces (metals, ceramics, and glass)

Areas of targeted research of the group

  • Failure analysis in industrial applications including the design of corrective actions

  • Characterization of physical and mechanical properties at temperatures from -196°C to 1500°C

  • Support in the development of material models for numerical simulations

  • Design of quality control procedures and setting of their parameters
