Prediction of risk of fracture in the tibia due to altered bone mineral density distribution resulting from disuse : a finite element study [PDF]

, 2014
The disuse-related bone loss that results from immobilisation following injury shares characteristics with osteoporosis in postmenopausal women and the aged, with decreases in bone mineral density (BMD) leading to weakening of the bone and increased risk

Nonlocal Criteria for Brittle and Quasi-Brittle Fracture of Geomaterials and Rocks

E3S Web of Conferences, 2018
Nonlocal criteria are used for prediction materials and rock mass failure near stress concentrations (pores, faults, openings, excavations). A common property of nonlocal fracture criteria is the introduction of the intrinsic material length ...

Computational multi-scale analysis of simultaneous processes of delamination and damage accumulation in laminated composites

Fracture and Structural Integrity, 2019
When studying mechanical behavior of structures made of laminated polymer composite materials, issues related to their relatively high susceptibility to damage, such as delamination, fiber breakage and matrix failure, play significant role.
