Identification of the length scale parameter of simplified strain gradient elasticity from standard Mode I fracture tests
Recently, it was shown that additional material constants of strain gradient elasticity (SGE) can be identified for brittle and quasi-brittle materials based on the analysis of experimental data on the crack size effect.
