The effects of stress triaxiality and strain rate on the fracture strain of Ti6Al4V
Engineering Fracture Mechanics, 2019Abstract The fracture strain is known to be affected by the stress state and strain rate. To measure the fracture strain over a wide range of stress triaxiality and strain rate, a rectangular hat-shaped specimen is designed. This specimen can be tested at low rates with a conventional load frame and at high rates with a Split Hopkinson Pressure Bar ...

Perren’s Strain Theory and Fracture Healing
2020The healing process of fractures depends on their biomechanical environment. The distinct knowledge and understanding of the biomechanical influence on fracture healing is the basis of the definition of the treatment strategy. The primary goal in treating a fracture is to achieve prompt and functional recovery of the injured limb.

Bone dynamics: Stress, strain and fracture
Journal of Sports Sciences, 1987Bone is a dynamic tissue whose functional mass is controlled by the balance between the endocrine drive towards bone resorption and the mechanically-engendered drive towards bone formation. Strain is the key intermediate variable between loading forces and bone remodelling. Animal studies have shown that static loading of bone has no osteogenic effect;

Stress/strain variability in fractured media: a fracture geometric study
Geotechnical and Geological Engineering, 2021The presence of natural fractures in fractured media plays a vital role in the in-situ stress state, which is predominantly influenced by tectonic stresses and local perturbations. Fracture orientation, wellbore stability/orientation, and permeability anisotropy are strongly dependent on local stress variations.

Sprains, Strains, and Fractures
Journal of Consumer Health on the Internet, 2017ABSTRACTSprains, strains, and fractures are common in all age groups, but individuals have little or no information about what to expect until it happens to them or someone they know. These injuries can occur in a flash, but the recovery can take days, months, or sometimes even longer.

Representation of Damage with Fracture-Strain
Applied Mechanics and Materials, 2014Under the influence of stresses and strains damage is progressively accumulated in the material leading to full damage viz. fracture corresponding to a critical damage parameter. The damage parameter varies in between zero and unity inclusive of both the values corresponding to non damaged and fully damaged condition.

Fracture in strain gradient elasticity
Metals and Materials, 1998Recent experiments have shown that the microscale material behavior is very different from that of bulk materials, and displays strong size effects when the characteristic length associated with the deformation is on the order of microns. Conventional continuum theories, however, can not predict this size dependence because they do not have an ...

Studies on Stress and Strain in Treatment of Fractures
The Journal of Bone & Joint Surgery, 1964The care of older patients is challenging and fraught with pitfalls, but the orthopaedic surgeon has the opportunity to give the elderly patient a gift that is of the highest value at that time of life, the chance to function better and more independently.
