How to estimate the Hertzian conoidal crack angle and length observed during indentation of brittle solids by a spherical indenter?

A simple crack system (Figure 1) can be readily studied to estimate the Hertzian conoidal crack angle and length, and also the stress intensity factor. This is a 3-D brittle elastic half-space...

Can we definitely believe in the existence of an electric potential round a dislocation in a metal that originates from the dilatation of lattice?

A connected question is: what is known (or measured experimentally) about the electromagnetic fields round an elastic-plastic crack that propagates quasi-statically in metallic materials? Based on...

I wonder whether the solution of the attached singular integral equation has been used in a previous work involving the interface crack under load?

This singular integral equation, whose solution is also given, is basic in a class of problems involving the interface crack under load. In order to give proper credit to former endeavors, please...

Does anyone have experience with predicting the failure surface in brittle fracture?

POSED PROBLEM: Apply a remote general loading (mixed mode I+II+III) to a large fracture specimen. Find the achieved fracture surface corresponding to the applied loading. We consider large cracks...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
