Dear Members,

I am very new to field of nanoindentation and my question might appear too simple.

I am indenting an elastic - plastic material (polymer blend) with spherical indenter. I am well verse with hertz contact mechancis theory and indentation theories like Oliver & Pharr, JKR, DMT and few others.

Sponsored by the National Science Foundation and the NSF Institute for Mathematics and its Applications, the University of Minnesota (Minneapolis, Minnesota, USA) is hosting a workshop on the boundary element method (BEM) April 23-26, 2012. This workshop consists of a two-day short course and a two-day colloquium on advances in the BEM with educational and industrial applications. Researchers and engineers from around the world, as well as students (both graduate and undergraduate) are invited to participate in this workshop.

Novacam 3D Profilometer Software

The Novacam three dimensional software programs are used with all Novacam Profliometers. The program permits the consumer to define how big the region, or line to be measured, along with the lateral resolution from the measurement.

Novacam's high end Data Acquisition Profilometer Software programs are incorporated with all of MicroCam non-contact profilometers.

Using a fiber-based optical profilometer NASA measures the thickness of liquid nitrogen in cryogenic chambers at its Propulsion Systems lab because these profilometers use fiber-based probes which can withstands the extreme environment, can be located hundreds of meters away from the interferometer and fit in the tight chamber which standard full-field profilometers with a human operator could not. The signal quality stays constant over the distance.

Hi All,

How can we compute the derivative of metric tensor on one manifold with respect to metric tensor on another menifold?

how to mesh two sucessive volumes with different meshing

i've modeled a column as a volume

i need a closer or finer mesh near the junction of beam

anyone pls guide me on this issue???

Hello,

Can anyone send me the paper by P A Cundall and RD Hart.Title of paper is NUMERICAL MODELLING OF
DISCONTINUA.It came in Engineering Computations journal paper (1992).I need it for my research work. thank you. rajeshpnair [at] gmail.com
