I am currently working on design optimization of nondeterministic systems and
would like to find realistic tolerances for the values of material
properties. Does anyone know of a (standard) reference for material
values that is probabistic or at least shows a range of values?
i have relations for tensile and bending stress in a rectangular plate due to a central surface crack for a constant thickness plate . i need to have these relations for a varying thickness plate . can any body help.
Dear all,
I have one question here. A blade is mounting on a rigid disk's outer rim. The disk is rotating at a variable angular speed. The system is used to model a turbine wheel with a blade mounted on it when the engine is ramping up or shuttng down.
The thing I want to calculate is the blade tip deformation in tangential direction during this engine ramp up -steady state -shut down process. Does anybody know how to use ANSYS to model it?
Dear Colleagues:
As a part of the 16th US National Congress of Theoretical and Applied Mechanics conference (from June 27 to July 2, 2010 at Penn State University), we are organizing a symposium on the multi-physics, or the coupling among physical domains (thermal, electrical, mechanical, magnetic, optical, chemical to name a few).
In this paper we formulate a geometric theory of thermal stresses.
Given a temperature distribution, we associate a Riemannian
material manifold to the body, with a metric that explicitly
depends on the temperature distribution. A change of temperature
corresponds to a change of the material metric. In this sense, a
temperature change is a concrete example of the so-called
referential evolutions. We also make a concrete connection between
our geometric point of view and the multiplicative decomposition

Can anyone help point me to publicly-available fatigue or fracture test data? I am interested in obtaining a variety of data for statistical processing. It seems many authors have used the data collected by Virkler and Hillberry which seems to be widely used, but I have not found raw data for their tests so far; is this data available somewhere for me to use? Any help is very appreciated.

Welcome to the forum! Discussion topics were suggested initially as follow:
Metal foams, cell deformation (bending, buckling, plasticity and fracture), constitutive stress-strain behaviour of cellular materials, energy absorption, hypervelocity impact, shock wave behaviour, 1D shock modelling, shock attenuation, shock enhancement, Material Point Method (MPM) simulation and microscopic tomography experimental observation;
and later were extended to many related:
A growing number of mechanicians are entering the field of soft materials, such as polymers, gels, and tissues. While they interact with researchers in technical societies traditionally identified with the field, they also maintain connection with researchers in applied mechanics.
