Plane wave diffraction by a rational wedge [PDF]

open access: yes, 1986
In this paper new expressions for the acoustic field produced when a plane wave source of sound is diffracted by a soft, hard or mixed soft/hard wedge whose angle can be expressed as a rational multiple of are given. The solution is expressed in terms of

Evaluation of new multiaxial damage parameters on low carbon steel [PDF]

open access: yesFracture and Structural Integrity, 2017
Most mechanical components are subjected to the complex fatigue loading conditions, where both amplitude and direction of loading cycles change over the time. The estimation of damage caused by these complex loading scenarios are often done by simplified

Comparison between SSF and Critical-Plane models to predict fatigue lives under multiaxial proportional load histories [PDF]

open access: yesFracture and Structural Integrity, 2016
Materials can be classified as shear or tensile sensitive, depending on the main fatigue microcrack initiation process under multiaxial loadings. The nature of the initiating microcrack can be evaluated from a stress scale factor (SSF), which usually ...

Explicit microscopic fatigue analysis of forged components [PDF]

open access: yesComputer Methods in Materials Science, 2007
Numerical modelling of fatigue behavior for anisotropic structures has become critical for design applications. This is particularly true for forged components due to the intrinsic anisotropy of the material resulting from the process.

Slow motion of a sphere towards a plane through confined non-Newtonian fluid [PDF]

open access: yes, 2011
The time needed for the contact of two spheres or a sphere with a rigid plane is mainly controlled by the hydrodynamic drainage of the film located in the gap as long as its thickness is out of range of the Van der Waals interactions.

Development of Attitude through Critical Thinking [PDF]

open access: yes, 2017
No doubt, across the world, advantages of critical thinking in education motivated educators focus on developing the critical thinking ability and traits among students more than ever before, yet ample evidence from literature has shown the lack of ...
