mesh free +orthogonal transform method +free vibration
Hi
I want to impose SS-F-SS-F or F-F-F-F for boundary condition of rectangular plate with element free galerkin method and with
ortogonal transform method(G.R Liu and chen 2001) for imposing B.c.
How can I do that?
for F-F-F-F how can I impose B.c? when I do nothing for imposing B.c ,I will have 3 extra natural frequency
the first complex and second and third near zero. how can I solve this problem
thanks
vielen dank

Survey on XFEM: is XFEM good at characterizing Failure rather than Fracture?
Would like to hear your expertise/user/non-expert/sceptic comments on XFEM. Here are some of the challenges. Would like to hear your relections.
1. Can XFEM be utilized in characterizing Failure rather than Fracture?
2. What sort of challenges XFEM still have with respect to Fracture Mechanics?
3. How the Fracture mechanics benefit the industry, from the perspective of strcutural integrity?
4. Failue investigations vs. Fracture investigations: benefit to industry?
5. Academist vs Engineer: Perspective on XFEM
Water Content In Exhaust Gas (Diesel Fuel)
Hi everyone,
I would like to know if anyone would be able to help me calculate(or measure) accurately the Moisture Content / Water vapour content in the Exhaust Gas of an Engine.
I would like to know if anyone would be able to help me calculate(or measure) accurately the Moisture Content / Water vapour content in the Exhaust Gas of an Engine.
I wish to determine the components of the Exhaust Gas for a Combustion Chamber(so that I am able to calculate the Gas Constant of the Exhaust Gas) and
I have been able to measure the values of Oxygen(in %), Carbon di oxide(in %), Carbon monoxide(in PPM), NOx (in PPM).

The Idaho National Laboratory has an opening for a Postdoctoral Appointee in the area of laser-based characterization of mechanical and thermal properties. This position is co-sponsored by the Fuel Cycle Research and Development program and the Center for Materials Science of Nuclear Fuel. The candidate must have completed a PhD degree in Materials Science, Physics, Mechanical engineering or a related field. The candidate should have a strong background in the development of continuum based models and/or a strong background in optics. The main objective of this proje
Warpage Measurement of PCB With 3D Profilometry
Flatness measurement of electronic parts and assemblies, or PCB’s, has become increasingly critical as geometries become smaller: finer pitches, smaller solder ball volumes, thinner substrates, etc. Additionally, processing temperatures vary and can play a major role in PCB warpage and or planarity defects. As a result, accurate flatness measurement, using a profilometer, has become vitally important to warpage characterization and planarity measurement.
Charpy Vs Gardner test
Hi ... what is the difference in functionality between charpy (a simply supported specimen(notched/unnotched) is hit by a swinging pendulum)and gardner test (a simply supported specimen(notched/unnotched) is hit by a vertical free falling mass guided by rails) ....
1.What is the loading pattern in the point of contact between the specimen and the setup?
2.Why fracture pattern varies between the two test setups for similar specimen with same impact velocity, Which parameter is responsible for the variation in fracture type.
Crack length in fracture mechanics
Hi,
I have modeled a beam with a hole in it in ABAQUS. I use of FRACTURE MECHANICS and FINITE ELEMENT METHOD for perdiction of failure load of beams with holes. I am wondering is it a correct assumption to assume a fixed crack length for one beam with varying hole position or not?
It have assumed that a fixed crack length for a beam with varying location of hole along the beam.
Am I correct?
Thank you,

SIMULIA announces new features in Abaqus 6.10
For those of you looking for FSI simulation on Abaqus platform, recently Simulia has announced the new features in release 6.10, which introduces the capability for performing Computational Fluid Dynamics (CFD) simulation.
So it enables users to perform coupled physics simulations with
Abaqus/Standard and Abaqus/Explicit, such as fluid-structure
interaction between human tissue, a medical device, and fluid flow, more information:

Stiffness of a beam
Hi,
As a part of my research, I would like to break down a simply supported beam to two beams shown in the attachement. I expect to remove the bond and use of springs for transforming deformation of upper beam to lower beam. What could be the stiffness of springs which could be used in new model?
Thank you for your comment,
