Low velocity impact modeling in composite laminates capturing permanent indentation [PDF]
, 2012 This paper deals with impact damage and permanent indentation modeling. A numerical model has been elaborated in order to simulate the different impact damage types developing during low velocity/low energy impact.

Traumatic Microhemorrhages Are Not Synonymous With Axonal Injury
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Diffuse axonal injury (DAI) is caused by acceleration‐deceleration forces during trauma that shear white matter tracts. Susceptibility‐weighted MRI (SWI) identifies microbleeds that are considered the radiologic hallmark of DAI and are used in clinical prognostication.

Geomechanics and Geophysics for Geo-Energy and Geo-ResourcesPrefabricated fracture dip angles and openings are important factors affecting the damage pattern and breakage mechanism of fractured rock. In order to investigate the fracture mechanism of fractured hard rock under the interaction of different fracture ...

ALE-based ductile damage and fracture [PDF]
, 2009 Mixed methods have been used with success in finite strain elasto-plastic with damage for decades. The subsequent stage is now dealt with enrichment methods, either local such as SDA or global such as XFEM.

Influence of surface tension in the surfactant-driven fracture of closely-packed particulate monolayers [PDF]
, 2017 A phase-field model is used to capture the surfactant-driven formation of fracture patterns in particulate monolayers. The model is intended for the regime of closely-packed systems in which the mechanical response of the monolayer can be approximated as

Arthritis Care &Research, EarlyView.Objective Australian evidence on lived and care experiences of chronic musculoskeletal shoulder pain (CMSP), irrespective of disorder classification or disease, is limited. However, such evidence is important for person‐centered care and informing local service pathways and care guidelines or standards.

Computer simulation of fatigue under diametrical compression [PDF]
, 2007 We study the fatigue fracture of disordered materials by means of computer simulations of a discrete element model. We extend a two-dimensional fracture model to capture the microscopic mechanisms relevant for fatigue, and we simulate the diametric ...

Arthritis Care &Research, EarlyView.Objective Reports have linked both high and low serum uric acid (SUA) levels to adverse health outcomes. This study aimed to establish a reference interval for SUA in older adults and assessed its association with clinically relevant outcomes in relatively healthy, community‐dwelling individuals aged ≥70 years old.

Damage-driven fracture with low-order potentials: asymptotic behavior, existence and applications [PDF]
, 2018 We study the $\Gamma$-convergence of damage to fracture energy functionals in the presence of low-order nonlinear potentials that allows us to model physical phenomena such as fluid-driven fracturing, plastic slip, and the satisfaction of kinematical ...
