What do
Guitar Strings Have to do With Dynamic Response?
Tightening
guitar strings to change the sound uses the same principle as tightening head
bolts to change the dynamic response of an engine block assembly. This is
stress stiffening and it affects the dynamic response of a structure. One of
the fundamental components in assessing nonlinear static stress is stress
stiffening, but it is also the most overlooked when evaluating the steady-state
dynamic response of engine assemblies.
We at ADINA R & D are looking for a Research & Development Engineer in Solids and Structures — general
finite element development. A PhD in applied mechanics or a related
discipline is highly desirable for this position. Applicant must have excellent
knowledge of finite element methods and good programming skills (Fortran
or C/C++).
The CEMAM workshop will be held at KAUST from July 1st to 3rd 2013. The event will be focused on the mechanics of solids and structures with applications to composite materials.
The main themes of this
workshop will be:
Hey all,
I am trying to use Drucker Prager plasticity with Tension hardening model for my material in Abaqus. In addition, I want to use the Drucker Prager creep with user defined (user) law that is via creep subroutine. But when I try to choose the Drucker Prager creep in the Abaqus CAE, it gives an error, "not all required arguments specified; expected 1, got 0." I am not able to follow what arguments it is asking for when I am using a user defined law. Any help regarding the same will be greatly appreciated. Thank you.

Abstract:
Cable and Overhead Electrical Conductor mechanical models are closely related. This can be seen from a recent review (January 2013) by Spak, K., Agnes, G. and Inman, D. : Cable Modeling and Internal Damping Developments, in the ASME journal Applied Mechanics Reviews, Vol. 65. The 18 pages paper, with its 86 references, has an interesting section on bending stiffness, with a rather (comparatively) extensive presentation of Papailiou’s stick-slip model. Use of the Coulomb spring-slider model for internal damping prediction is also presented.
