Interesting topics of material fracture/deformation?

SUMMARY

The discussion highlights key research areas in material fracture and deformation, focusing on specific materials such as aluminum alloys, copper alloys, and stainless steels. Notable topics include the influence of grain boundary misorientation on intergranular fracture and numerical studies on bifurcations in multi-void growth in nonlinear elasticity. Advanced modeling techniques such as phase field modeling and density functional theory are emphasized, along with critical simulations of elastic-plastic behavior, including visco-elasticity and visco-plasticity. Additionally, the challenges of stress-corrosion cracking, particularly intergranular stress corrosion cracking (IGSCC) and irradiation-assisted stress corrosion cracking (IASCC), are discussed in the context of improving power system efficiency.

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.
