Interesting topics of material fracture/deformation?

  1. Oct 26, 2018 #1
    What are some interesting topics in the field of material fracture and deformation? Maybe a newer area of research?

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.

    That's a rather broad subject area, since one can focus on particular types of materials, e.g., aluminum alloys, copper alloys, steels and stainless steels, nickel or cobalt alloys, ceramics, cermets, composites, plastics/polymers, glasses, . . . . , and even specific alloy systems, e.g., austenitic, ferritic, martensitic or duplex alloy systems.

    One can browse a journal such as the International Journal of Fracture and find the latest topics of interest, e.g.,
    Influence of grain boundary misorientation on intergranular fracture
    A numerical study on bifurcations in multi-void growth in nonlinear elasticity

    There is a lot of work with phase field modeling and density functional theory.

    Simulating the elastic-plastic (including visco-elasticity and visco-plasticity) has become critical.

    Then there are areas of stress-corrosion cracking (particularly intergranular stress corrosion cracking (IGSCC)) and in the nuclear reactor environment, irradiation-assisted stress corrosion cracking (IASCC). In order to obtain greater efficiency from power systems, engineers want to increase temperature and stress, but have to balance those requirements against creep, corrosion, fatigue and fracture. In a given alloy system, there is still a need to understand the influence of composition (and microstructure), even down to individual elements (including impurities), on the elastic-plastic behavior, and fracture toughness, of the particular alloy in its intended service environment.
