Size effects in fracture mechanics: A detailed investigation on crack growth at the micro- and mesoscale

Conference Dates

October 2 – 7, 2022


Fracture mechanics are strictly regulated by standards. This includes limitations of specimen size as a function of plastic zone size. Since the size of the plastic zone mainly depends on the material itself, the established macroscopic test procedures cannot be easily downscaled when sample size decreases to the microscale. With advances in micromechanical testing, the classical size effect in metals, whereby the strength increases as specimen dimensions become smaller, has been studied in detail.
