Viscoplastic constitutive models for zero-thickness interface elements, formulation and applications [PDF]
, 2019 An energy-based work-softening visco-plastic model for zero-thickness interface elements has been developed as an extension of an existing elastic-perfectly-viscoplastic formulation.

Size Effect in Fracture: Roughening of Crack Surfaces and Asymptotic Analysis
, 2002 Recently the scaling laws describing the roughness development of fracture surfaces was proposed to be related to the macroscopic elastic energy released during crack propagation [Mor00].

The Archimedes’ Constant, π Seen by Mechanical Engineers
Mathematical and Computational Applications, 2019 Probabilistic engineering mechanics is used to relate the value of π with one of the main parameters in fracture mechanics. It proposes an engineering method to obtain the value of it from engineering data without involving any geometrical ...

Modified Fracture Mechanics Approach for Hydraulic Fracturing Stress Measurements
Geofluids, 2020 Hydraulic fracturing (HF) test has been widely used to determine in situ stress. The use of a conventional continuum method for this purpose has raised considerable controversies concerning field tests, particularly in the determination of the maximum ...

Dental Materials, 1995 The principles of linear elastic fracture mechanics (LEFM) were developed in the 1950s by George Irwin (1957). This work was based on previous investigations of Griffith (1920) and Orowan (1944). Irwin (1957) demonstrated that a crack shape in a particular location with respect to the loading geometry had a stress intensity associated with it.

Long‐Term Evaluation of Givinostat in Duchenne Muscular Dystrophy, and Natural History Comparisons
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives This ongoing, open‐label extension study is evaluating the long‐term safety, tolerability, and efficacy of givinostat, a Class I and II histone deacetylase inhibitor, in patients with Duchenne muscular dystrophy (DMD). Methods The recruited patients completed one of two prior clinical studies (one Phase 2 and one Phase 3 [EPIDYS ...
