Deadline for Abstract submission: November 3. See www.mrs.org/spring2009.  A symposium entitled "Architectured Multifunctional Materials" will be organized at the MRS-spring meeting in San Francisco next year (April 13-17, 2009). For details see below and attached file.

This is supposed to be a very classic analytical solution in applied elasticity. Forgive me if this is a repost or some correction has been made before. I had a hard time with it.

Problem statement:  uniform pressure is applied on cirular area (radius=r) on top of a semi-infinite plane. Find the vertical deflection.

We got discrepancy between FEA solution and analytical solution which I found from different textbooks (famous and non-famous): Deflection within the circle is good, however, no good outside the circle.

I am modelling melting by element death.  I have a cold (melting) rectangle with a hot fluid convecting at the exterior.  I am using a do loop so that time increases at each loop.  I define a "melting" temperature, so that elements are killed off when they achieve a specified temperature.  

I  have done modal analysis and when ANSYS asked to input the start and  end frequency i typed 150 as my starting frequency and 2000 as my ending frequency. No of modes to extract 10 and no of modes to expand 10. Due to no of modes ANSYS has only displyed 10 results. When i entered in postproc and results summary only 10 results were displayed and starting frequency was 150.01 to 150. 39. Now if i want to see all the frequencies how is this possible???Should i maximise the no of modes or is their any other option to view the results???

Hi Every body

I am Dhaneshwar Mishra, a PhD student working in the area of fracture mechanics, basically fracture failure of interfaces of bimaterial, composite layers etc. I am regular reader of IMechanica and got lots of insights by reading different postings on it. I am trying to model the interface in ANSYS 10.0 with their Interface element INTER204. While searching this element in Ansys element library, i could not find it. Will some body guide me to model interface of composite layers using the concept of cohesive zone modelling?

Thank you

Recent events about the financial crisis and generally spread turmoils on Economics and Financial Environments  lead me to these conclusions.

Critical Speed:  informations, a key issue on finance, reached a critical speed. Maybe this is the "first" critical speed of the system. Speed of informations has reached the same order of magnitude of people's judgement (executives and investors more than others) so there's a sort of over-reaction about actual events.
