For both mechanicians and physicists, linking continuum concepts to the underlying microscopic characteristics of materials has remained a major preoccupation. Certainly, with the recent advent of the so-called "multiscale" modeling approaches, this topic has been brought to a sharp focus. Cauchy stress is one such continuum concept that has courted a fair amount of controversy.

Hello everyone,
As reported in some references, Maxwell stress of a dielectric elastomer subjected to electric field can be determined by the following formula
P=e*E^2 (1) -------e=e0*e1, e0 is the dielectric permittivity of vacuum, e1 is the relative dielectric permittivity of the elastomer, and E is the applied electric field.
Hello,
I seek help from the forum regarding the following. Because I am very new to mechanics.
I have a continuum damage mechanics model with me. I have set up a problem of a typical three point bending test on a notched beam. The notch in the center of the specimen and extends from the bottom face up to the middle of the thickness. It is a plane stress problem. Now I want to simulate load-displacement curve obtained from the experiment (s).
Hello everyone,
I am currently a doctoral candidate at Louisiana State University, and expect to complete my PhD degree requirements by Fall 2010. My doctoral dissertation is conducted under the direction of Prof. M. M. Khonsari, and looks at the use of a relatively new methodology for the fatigue of structural components. In my research, I developed an effective and new criterion for fatigue life monitoring of the components subjected to cyclic loading based on thermodynamic entropy concept.
Dear Friends,
I need help for modeling RC beam, fracture mechanics of plain concrete and measurement of concrete creep with ANSYS or ABAQUS. I would really appreciation if you could send me those mentioned PDFs.

Thanks
