about critical thickness theory
who can tell me more about the critical thickness theory ?I will be very excited if you can introduce some reference to me.I know that critical thickness theory is solved rigorously and ursed to validated a useful approximation which is combined with slip distance theory modified for a finite structure size . (physical life review letters :elastic limit and strain hardening of thin wires in torsion)
The use of IOSO Optimization and ABAQUS at Civil Structures of NPP (from ABAQUS Users' Conference)
At the stage of NPP civil structure design for determination of stress-strain state (SSS) at static and dynamic loading ABAQUS is widely used. Hereto the floor response spectra are determined for calculation of loadings on the equipment at special dynamic impacts (seismic, air shock wave, aircraft crash). In case if the obtained characteristics of SSS or spectral accelerations exceed maximum permissible values, designers take actions on strengthening the corresponding structural components.
Human conditioning
Instead of cooling a whole room some mechanism should be devised to cool only the human body thats only d requirement and can save energy its like mobile u can have it when u need.
fracture energy for hashin damage evolution using Abaqus
hi everyone,
i'm modelling the impact on the composite carbon/epoxy using Abaqus 6.9.
i have the questions:
when i use damage evolution for hashin damage criteria, i need the values of the fracture energy: longitudinal tensile fracture energy, longitudinal compressive frecture energy, transverse tensile fracture energy, transverse compressive fracture energy. i'm suggested to use the values as 12500, 12500,2500,2500. Are these correct? i dont know how to evaluate these values. Is there any suggestions?
wait for reponse.

Are Linear and Angular Momenta Interconvertible?
To the best of my knowledge, the two momentum conservation principles, namely, the conservation of linear- and angular-momentum, operate completely independent of each other. For an isolated object, there is no possibility of conversion of one form of momentum to the other.
Workshop & trip to Ferrari MilleChili lab and Galleria Ferrari with 50 students from Politecnico di Bari
On friday we had a wonderful trip to Modena, at the University of Modena's Millechili
Lab with which I collaborate also for the MilleChili journal Millechili Journal -- weight reduction in vehicle design.
In collaboration with Ferrari SpA project.
Spectacular torsional-flexural autovibrations of a Volga bridge
The autovibrations of the bridge over Volga river in the city of Volgograd(Russia) were filmed (not by me) today on 05/21/2010. The amplitude reachedabout 1 m. The bridge opening was just six months ago...
Apparently, either the bridge frame drag was too high or torsional stiffness / damping too low.
Postdoctoral Position in Run-out Table Heat Transfer Studies at the University of British Columbia
The Centre for Metallurgical Process Engineering at the University of British Columbia (UBC) is recruiting qualified applicants for the position of Postdoctoral Fellow. This is a unique position in industrially oriented research on heat transfer studies during run-out table cooling of advanced high strength steels. In detail, the work will involve the development of a run-out table cooling model based on analyzing results obtained from heat transfer studies using the unique pilot scale run-out table located in the Advanced Materials and Process Engineering Laboratory (AMPEL) in UBC.
