ASSOCIATE or ASSISTANT PROFESSOR
EXPERIMENTAL MECHANICS OF MATERIALS
The Department of Mechanical Engineering at the University of Wyoming invites applications for a tenure-track faculty position. Applicants are sought at the Associate or Assistant Professor level with expertise in experimental solid mechanics. Areas include but are not limited to the study of heterogeneous material systems, biomaterials, nanomaterials, thin films, fracture, fatigue and damage.
Hi Every one,
Dose any one know where I can get a good Manual/document on "detecting onset of fracture using acoustic emission"?
I heard some say this method of detecting onset of the fracture has lots of error and is not accurate..is this true? if yes,why? Are there other methods to find the onset of the fracture in an experiment?
Hi,
I am a graduate student. I want to start learning Molecular Dynamics
specially in respest to Continuum Mechanics/Fracture Mechanics. Can anybody give me some
light about how to start or which textbook to start with?
I want to use Large-scale Atomic/Molecular Massively Parallel
Simulator (LAMMPS) package (C++ version). Is there any group/person who is using this package? I need some help.

Within the last two weeks the US National Science Foundation (NSF) published not one but two studies on (a) the attitudes of scientists and engineers to the changing world of publication, and (b) the relative global productibity of US science & engineering as measured by journal publication.
These are not dense 500 page reports, but short, readable (10-15 min.). I think iMechanica readers will find them relevant and interesting:
How can we see load dipslacement cyrve of residual stressed material. I mean I m interested in extracting indentation properties from ABAQUS for material which has got some pre stress in terms of residual stress. What is procedure of assigning residual stress to some material in ABAQUS?
For hardware based method, you can use an independent timer to trigger off the counter to measure the number of speed pulses in a suitable frequency, such as 1MHz. In that case, the time interval you obtained is so small that it apporaches to zero.
Instantaneous Angular Speed (IAS) is investigated for last 10 years in Condition Monitoring. The content of IAS is coming from angular speed. If the time taken is reduced apporaching to zero, we can measure the angle travelled to extract IAS, or if the angle travelled is reduced to zero, we can measure the time elapsed to extract IAS.
