Analysis of Mixed-Mode I/II/III Fracture Toughness Based on a Three-Point Bending Sandstone Specimen with an Inclined Crack

open access: yesApplied Sciences, 2021
The crack-propagation form may appear as an arbitrary mixed-mode fracture in an engineering structure due to an irregular internal crack. It is of great significance to research the mixed-mode fracture of materials with cracks.

Crack tip fields in elastic-plastic and mixed mode I+II+III conditions, finite elements simulations and modeling [PDF]

open access: yesFracture and Structural Integrity, 2015
This paper is devoted to the analysis of the load path effect on I+II+III mixed mode fatigue crack propagation in a 316L stainless steel. Experiments were conducted in mode I+II and in mode I+II+III.

Electronically Tunable Mixed-Mode Universal Filter Employing a Single Active Block and a Minimum Number of Passive Components

open access: yesApplied Sciences, 2020
A recently developed active building block, namely Voltage Differencing Extra X Current Conveyor (VD-EXCCII), is employed in the design of multi input single output (MISO), electronically tunable mixed-mode universal filter. The filter provides low pass (

Analytical Modeling of the Mixed-Mode Growth and Dissolution of Precipitates in a Finite System

open access: yesMetals, 2019
In this paper, a novel analytical modeling of the growth and dissolution of precipitates in substitutional alloys is presented. This model uses an existing solution for the shape-preserved growth of ellipsoidal precipitates in the mixed-mode regime ...

Crack Front Segmentation and Facet Coarsening in Mixed-Mode Fracture [PDF]

open access: yes, 2015
A planar crack generically segments into an array of "daughter cracks" shaped as tilted facets when loaded with both a tensile stress normal to the crack plane (mode I) and a shear stress parallel to the crack front (mode III).

A Tunable Balanced Coupler With Improved Phase Balance and Extended Bandwidth

open access: yesIEEE Access, 2019
This paper proposes a balanced coupler with improved phase balance and extended bandwidth for a wide range of tunable power-dividing ratios. This differential coupler uses only two varactors and can demonstrate tunable power-dividing ratio and quadrature

Extension of the CJP model to mixed mode I and mode II [PDF]

open access: yesFracture and Structural Integrity, 2013
The present authors have previously proposed a novel ‘plastic inclusion’ approach for dealing with the local plasticity which occurs at the tip of a growing fatigue crack.
