Biomechanical evaluation of different strain judging criteria on the prediction precision of cortical bone fracture simulation under compression

Frontiers in Bioengineering and Biotechnology, 2023
Introduction: The principal strain or equivalent strain is mainly used in current numerical studies to determine the mechanical state of the element in the cortical bone finite element model and then perform fracture simulation.

From Brittle to Ductile Fracture in Disordered Materials [PDF]

, 2010
We introduce a lattice model able to describe damage and yielding in heterogeneous materials ranging from brittle to ductile ones. Ductile fracture surfaces, obtained when the system breaks once the strain is completely localized, are shown to correspond

Tensile strain and fracture of snow [PDF]

Journal of Glaciology, 1980
Abstract Measurements over several hours of the tensile strain of snow have been carried out, and the strain-rate e can be expressed in terms of stress σ, elapsed time t, and (Celsius) snow temperature T

Preparation, Microstructure Evolutions, and Mechanical Property of an Ultra-Fine Grained Mg-10Gd-4Y-1.5Zn-0.5Zr Alloy

Metals, 2017
In this work, the microstructural evolutions and mechanical properties of an as-cast Mg-10Gd-4Y-1.5Zn-0.5Zr (wt %) alloy during successive multi-pass equal channel angular pressing (ECAP) were systematically investigated by X-ray diffractometer, scanning

Deformation and fracture behavior in TRIP steels under static and dynamic tensile conditions

Journal of Materials Research and Technology, 2022
The present study sought to explore the deformation and fracture behavior of Quenching and Partitioning (Q&P) steel at five different strain rates (10−4 s−1, 1 s−1, 10 s−1, 100 s−1 and 1400 s−1).

Creep and Fracture in Concrete: A Fractional Order Rate Approach [PDF]

, 2002
The paper analyses the interaction between strain-softening and time-dependent behaviour in the case of quasi-static fracture of concrete. A viscous element based on a fractional order rate law is coupled with a micromecanical model for the fracture ...

Fracture healing monitored with strain gauges [PDF]

Acta Orthopaedica Scandinavica, 1992
We measured healing in 7 cases of surgical neck fracture of the humerus by applying a strain gauge measuring bar between the external fixation pins. Repeated measurements provided a healing curve for the individual cases. The gradual decrease in deflection of the fracture zone reached a plateau of about 50 percent after 2 to 4 weeks in 6 cases.
