Calculate bimaterial H-matrix for orthotropic material.
Hi
I have a question regarding calculating the B-matrix which is used to create the bimaterial H-matrix in the article: "Singularities, Interfaces and Cracks in Dissimilar Anisotropic Media" by Zhigang Suo, 1989.

The shape of the Eiffel Tower
I've got interested, since I am going with about 10 of my students to Paris for the Euromech conference I am coorganizing in July, by the design of the Eiffel Tower. Eiffel was a great engineer, and indeed his shape of the tower apparently comes from his ingenious idea of balancing weigth and wind pressure so that there is little need of foundations. WIKIPEDIA has an account of this design idea, and the resulting integro-differential equation.
Acurate Size Measurements of Nano Particles and Nano Pores Make Mechanical Understanding Easy
Encouraged by its current and prospective customers, Ebatco’s Nano Analysis and Testing Laboratory (NAT Lab) has expanded its nano/micro scale analytical and measurement capabilities significantly. More than ever before, customers can gain insights and comprehension of what is going on and why it has happened at the nano/micro scale.

Interfacial Fracture
These notes belong to a course on fracture mechanics
A body consists of two materials bonded at an interface. On the interface there is a crack. The body is subject to a load, causing the two faces of the crack to open and slide relative to each other. When the load reaches a critical level, the crack either extends along the interface, or kinks out of the interface.
Emden-Fowler Differential Equation
I input into MAPLE the following differential eq & it returned that it is classified as an Emden-Fowler Differential Equation:
r^2*F"+1/r*F'-k^2*F=0 where F is a function of r
MAPLE was able to generate a solution. I am attempting to figure out how this eq is actually solved & I typed in Emden-Fowler into the SEARCH window on this website & got ZERO results.
