Dear colleague, The third issue in 2012 (Volume 25, Issue 3) of Acta Mechanica Solida Sinica (AMSS) is now online. Welcome to this SCI-indexed journal <http://ees.elsevier.com/camss/> for rapid publication of your exciting results.
hi every one
i am modeling a reinforced concrete beam in ansys, but should i only applying the load or should i make a load steps?
and if i must make a load steps......how to do it?
please if any one can put a text file for commands used to model a reinforced concrete beam and make a load steps ......that would be great
best regards
Hi,
Concerning the Newmark method with central difference for an explicit resolution I want to know where the parameters beta and gamma come from ?
I have found this :
http://www.stanford.edu/group/frg/course_work/AA242B/CA-AA242B-Ch7.pdf
but how do these parameters appear ?
Using RADIOSS, the theory manual says the remainder of the taylor's series is computed using numerical integration but I don't know which rule is used.
There is an immediate opening for a Ph.D. student in the Department of Materials Science and Engineering at Missouri University of Science and Technology (Missouri S&T - formerly University of Missouri-Rolla). The Metallurgical Engineering program at Missouri S&T is one of the largest and most respected in the U.S. (http://mse.mst.edu).
The Ph.D. research project is about developing a coupled phase-field crystal plasticity model for predicting stress-strain-microstructures relations during deformation.
Attached herewith a classical paper by Hart on introducing a concept of constant hardness curves refuting that absolute strain should not be considered as a state variable.
The interesting part is he uses a stress relaxation test to prove the same. Stress relaxation test, here refers to a tensile test, where the test is stopped after say certain amount of plastic deformation. The stress drops a little, but the total strain is constant. However, it is argued that there is a small inelastic deformation, which is the cause of this load or stress drop.
