J Integral calculation for an Axisymmetric Problem with crack in Ansys
Hi all,
I am working on Crack growth analysis of Turbocharger wheel and shaft assembly. I have simulated it as an axisymmetric problem with fine mesh around the cracktip(in Ansys). Element used is Plane182.
I have to compare the K1 and K2 values obtained from both the Displacement Extrapolation Method and J-Interal method.
I got the K1 an K2 values at the cracktip location by defining path using displacement extrapolation method.
But, I was not able to get the Stress intensity factor values (K1 nad K2) using J-Integral Method.
Dynamic force on a closing mitre gate
I'm looking at the design forces acting on a vertically hinged mitre gate for flow control in a canal, (open channel flow). We know the maximum volumetric flow rate of the water flow when the gate is closing. How can I estimate the maximum force exerted on the gate as the water causes it to slam shut.
Overhead Electrical Conductors and High Intensity Wind
Effect of tornadoes on electrical power lines has been discussed by Sébastien Langlois in his M.Eng. thesis : “Design of Overhead Transmission Lines subject to Localized High Intensity Wind”. McGill University, Montreal, QC, Canada, 2007 (available on-line on the “Theses Canada” portal). Work presents various national and international standards (ASCE, Cigré, IEC etc.), historical cases, as well as models for numerical simulation.
Aeolian vibrations and fatigue of Overhead Electrical Conductors
An interesting presentation of the state of the question by Dr Louis Cloutier, in 2008.
Overhead Electrical Conductors
As a follow-up, here is a photograph of a (rather extreme) case of conductor fatigue.
link 8, introduced tensile curve and compression curve
Hi.
I'm working with the element link8 (Ansys 12.1) and I have to introduced the tensile curve and compression curve, but I don't know, How I have to introduced its???
I have worked with the comands: TB: aniso, miso,..., I think the best option is: TB, user, but How I have to introduced the values of tensile and compression curve?, when this are different.
File attachment is the tensile and compression curve to introduce
Thank you, Toni
Surface Boundary Measurement Using 3D Profilometry
In profilometer studies where the interface of surface features, patterns, shapes etc., are being evaluated for orientation, it will be useful to quickly identify areas of interest over the entire profile of measurement. By segmenting a surface into significant areas the user can quickly evaluate boundaries, peaks, pits, areas, volumes and many others to understand their functional role in the entire surface profile under study.
