FREQUENCY DOMAIN
hy everyone
Im working on dynamic explicit poblem.i am attemping to obtain frequency domain from time history of strain.
help plz

POST-DOC POSITION
Title : Experimental and numerical study
of the composite materials fatigue under multiaxial loadings
The Polymers and Composites Technology & Mechanical Engineering
Department of the Ecole des Mines de Douai (France) is currently offering a
postdoctoral fellow position aiming at studying the behavior of composite
materials under multiaxial loadings.
non linear frequency analysis
Hi,
I'm trying to run a frequency analysis of a composite beam with non-linear properties in Abaqus. Is it possible to make use of the non-linear properties in the frequency analysis. If so how can I do it?
Composite beam in this case refers to a combination of steel and concrete.
Any detailed contributions will be appreciated.
Thanks
Shot Peen Hardness With Nanoindentation
The intention of shot peening is ultimately to alter the mechanical properties of a given surface. By hitting the surface with controlled shot the surface will deform plastically. Proper Instrumentation, nanoindentation, will play a vital factor in achieving reliable and intended results.
Basic question regarding composite failure during impact
Hi everyone.. I am doing low velocity impact analysis on graphite/ epoxy
composite plate using abaqus. I have a basic question. During transverse
impact, when does a composite fail? The transverse tensile strength of
my composite is 45 Mpa, transverse compressive strength is 252Mpa,
Longitudinal tensile & compressive strengths are 1520 and 1590 Mpa
respectively. During my analysis, I got the Maximum von mises stress as
2093MPa at the point of impact, but still the failure criterion is not

Nonlinear Material Model using ANSYS
I am performing the static analysis on hydraulics component where I am using the nonlinear material properties with multilinear kinematic material model having yield ~150 ksi and ultimate strength ~210 ksi. However I am getting first principal stress as 280 ksi and von Mises(equivalent) stress ~ 240 ksi.
I checked for the directional stresses where I find the stress in axial direction as ~279 ksi.
Whether it is possible to have the stresses above the given material limit (in this case true ultimate strength is 210 ksi).
