The drivers for move of the rockets are designed in form that or the other version of the Laval nozzle.The reactive force of the traction which is created by such driver can essentially be increased if in the outer section of nozzle is placed an active shock wave of stretching (depression): then the reactive force of the traction becomes

A PhD position is available in the Department of Mechanical Engineering and Engineering Science at the University of North Carolina at Charlotte. The research project is on the multiscale modeling of the stress corrosion cracking. Candidates should have a strong background in continuum mechanics, finite elements and constitutive modeling. Programming experience in Fortran or C++ is required for this position. The starting date for this position is January 2017.
The Computational Mechanics group at The University of Iowa, led by Professor S. Rahman, is looking for two new Ph.D. students, who are capable of and interested in performing high-quality research on isogeometric methods and uncertainty quantification. The research, supported by U.S. National Science Foundation, requires building a solid mathematical foundation, devising efficient numerical algorithms, and developing practical computational tools, all associated with stochastic isogeometric analysis of complex materials and structures. A substantial background in solid mechanics with coding experience in finite-element or similar methods is a must; exposures to uncertainty quantification and probabilistic methods are highly desirable.
Dear All,
I am pleased to inform you that an International Scouting procedure for Tenure-Track faculty positions is now open at IMT Lucca.
The IMT School is collecting expressions of interest from exceptional candidates of all ranks in the following areas:
· Economics, Management and Data Science
· Computer Science and Systems Engineering
· Neurosciences
· Cultural Heritage
The second area includes computational mechanics.
Hi all,
I am doing crack modelling (XFEM) under moving compression and traction loading in Abaqus but I get warning regarding the crack under compression load as follows:
"THE LOADING CONDITION MIGHT MAKE MAIN CRACK UNDER COMPRESSION AT NSET "X" THE CRACK PROPAGATION DIRECTION CANNOT BE PREDICTED. A VALUE OF ZERO IS PROVIDED FOR IT."
Anyone facing the same issue?
Kind regards,
Omid
In ABAQUS, how to apply a pressure field using vdload subroutine on a newly produced surface after deletion of elements from the top surface where the pressure field was actually applied? Or in other words, how to define a new surface for applying a pressure field, where the surface on which the pressure was initially applied is deleted with the evolution of damage.
Hi
Can someone explain me what are these
1) Rigid wall energy &
2) Hour glass energy
These are in context of LS-dyna
Thanks!
Hi
I am new to EFG method. I cannot find any good resources in this topic in a introductory level.
Can someone suggest me resources to start with
Thanks in advance
