Microplastic Strain Hysteresis Energy as a Criterion for Fatigue Fracture
This materials science paper proposes an energy-based fatigue failure criterion using microplastic strain hysteresis energy, developing a relation between stress amplitude and cycles to failure. 'Microplastic strain' refers to small-scale plastic deformation in metals during cyclic loading and has no connection to environmental plastic pollution.
Micromechanical aspects of the effect of temperature and local plastic strain magnitude on the fracture toughness of ferrite steels
This materials science study examined how temperature and plastic strain affect the fracture toughness of ferrite steels at the microscopic scale. The term 'microplastic' here refers to microscopic plastic deformation in metal — this is an engineering study unrelated to plastic particle pollution.
