Hazard is defined as a chemical or physical condition that has potential to cause harm to human life, property or the environment and a reactive hazard has potential to initiate a reactive incident. It is an outcome of changes to chemical structure leading to rapid release of energy, heat and gaseous products leading to severe consequences e.g. fire, explosion, or toxic release.
A reactive hazard may involve:
Hello ,
I am doing the correlation between Ansys and Abaqud for a shroud of cooling module (solid 92-C3D10) .I find the coorelation is perfect in frequency , but when i do the powerspectral density analysis, i noticed a gap of 10-20% on the peak value of nodal von mises stress , i'd like to know the reason of the diffrence .
Thank You .
Hello!
I am
working on my master project, regarding post buckling of laminates with
piezoelectric layers.
Hi,
I am working on my post grads project, i would be very thankful if anyone does needful in this regard.
I need some suggestions in deriving out the non-linear governing equation for a simply supported flat rectangular laminated plate , here i considered a uniformly distributed load.
I have taken Von-Karman strains e(xx), e(yy), e(xy) with non-linear terms for a single term,
to derive the equilibrium equations of motion, is virtual principles of work or displacement necessary?
Hi,
Is principle of Virtual displacements employed to derive equations of motion for a laminted plate?
Is this useful for the non-linear analysis of plate through Classical plate theories ?
Would you please give me some suggestions?
Thanks in advance
Hi,
I am Sri Harsha from IITMadras.
I have been trying to do composite with 40 plies out of which 20 taper plies in 1 in 20 ramp.
It is giving error which I am sending in the attachment..
If
I am trying to work with 20 normal plies with no taper plies in it and only 20 taper plies separately
it is working but when I do combine these two it is giving error. I do not
know what was wrong in it. Can anyone please help me out in this. I have
to do this as soon as possible.
There has been an increase in the exploration of unconventional crude oils, which almost equal global conventional oil reserves - from bitumen through to heavy oils. Discuss the safety and environmental issues that arise from their exploration, and possible solutions.
The Macondo incident failed due to the failure of the BOP atop the Macondo well. The BOP was designed to activate and seal the well if control was lost, even in a “low probability, high impact event”, such as the blowout that occurred the evening of April 20, 2010. The report released from NAE/NRC, entitled “Macondo Well-Deepwater Horizon Blowout, lessons for improving offshore Drilling Safety”, summarized the known and suspected reasons for why the BOP failed:
Intructrion on how to link Abaqus and Fortran for running subroutines (In Linux-UBUNTu) including: intel c++ /Fortran and Abaqus: including:
a) The requirements, b) Installation of Intell C++ and FORTRAN on linux machine c) How to fix the graphic issue (Transluscent screen) in abaqus after installation d) How to link the Abaqus and Fortan for running subroutine (UMAT or VUMAT).
Hope it can be helpful. It is just a collection of information for
