A postdoctoral position is available in the area of interfacial mechanics of soft materials at Rutgers University working under the supervision of Prof. Cuitino. The position is supported by the National Science Foundation and industrial partners of the NSF Engineering Research Center for Structured Organic Particulate Systems (http://ercforsops.org/).
The Idaho National Laboratory (INL) Energy Resources Recovery & Management Department invites applications for one, or possibly two, post-doctoral research positions in the area of numerical simulations of coupled thermal-hydro-geomechanical processes in geothermal reservoirs. The position(s) will be available in October 2009 and will be renewable for up to 3 years. An earlier start is possible, depending on project development.
Hi,
I observed that with
periodic boundary conditions on unit concrete unit cell, when uniaxial load is applied structure
behaves as if it is constrained to move in lateral direction, when
shear or other traction laoding is applied it has displacement
compatible behavior i.e, parallel edges has periodic deformation
behavior. With these above behavior can I conclude that for uniaxial
loading I need not apply periodic BCs and simply applying roller is
sufficient on lateral edges or there is no need to apply and periodic
BCs for uniaxial loading.
Dear imechanica user,
As i know, stresses existing in the components suffering no any outer forces are called the residual stresses. To reply the reason why the residual stress appears in the component?
Could anyone answer this question for my understanding.
regards,
Arefin
I'm having a hard time trying to relate the the forces specified in the figure so that I can obtain the expression for the strain energy release rate.
For the 'L-opening load' P when acting alone, the energy release rate is given by:
G= (12*P2*L2) / (E*B2*h3)
For the '2L/3-opening load' P when acting alone, the energy release rate is given by:
G=(16*P2*L2) / (3*E*B2*h3)
Through this post I wish to share some recent results that provide new insights into the role of a defect-core in mechanics. Below is the abstract of the work, and the references and links to the preprints of articles. I look forward to your comments and suggestions.
Abstract:
Markus Buehler of MIT, Ioannis Chasiotis of UIUC, John Dabiri of Caltech, and Robert Wood of Harvard are among 100 recipients of this year’s Presidential Early Career Awards for Scientists and Engineers. Congratulations!
hello,
can 2 .db files ,that are already meshed, be opened in a ANSYS window if i do not have input codes?
thank you very much
best regards
