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.
ABAQUS (6.8, 6.9 EF) - Effect of the number of back stresses
Since ABAQUS 6.8, a new feature has been added to the combined hardening material input.
Let's assume a combined Kinematic and Isotropic hardening case, such as those happen in metals.
"Half cycle" uni-axial test results has been utilized to model the yield stress-plastic strain behavior as well as the Kinematic behavior of the metals.
In the same user interface, there is an option to choose the number of back stresses.
Is the number of 1 back stress is equivalen to the case of linear kinematic hardening (Ziegler's)?

About experimentl methods for observing the anisotropic plastic behavior of FCC alloy
I'm doing a research on anisotropic yield criteria for a FCC alloy and I have to do biaxial tensile experiments to get the yield locus in the biaxial stress space.I have two kinds of samples:
1. metal sheet with dimensions of 150mm x 70mm x 15mm(thickness);
2. rod with diameter of 20mm and length of 150mm.

Dear Sir,
Interactive Simulation Environments
I'm doing a literature review on Interactive Simulation Environments. Does anyone have any suggestions for interesting papers to look at?
And if you've written one and let me know, I might cite it :-)
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.
