difference between elastic limit and proportional limit

hi all,

can anyone explain about the following basic questions

1. me the difference between the proportional limit and elastic limit.

   Please dont give the definitions of both, i need some detailed explaination.

 2. How many natural frequency a object can have?

Regards

question on the design of a wide-flange beam

I am refering to the book - Mechanics of Materials by Beer, Johnston and DeWolf (McGraw-Hill) topic 8.2.

When we design a wide-flange beam, we must consider two conditions. First, the shear stress at the maximum shear section must not exceed the allowable shear stress. Second, the principal stress at the junction of the web and the flange at the section of the maximum moment must also be compared to the allowable normal stress. This is straightforward and clear to me.

Polymer materials analysis for damping in ansys

I want to find the material damping of polymer material through ansys, Is it possible to find the damping of a material damping by using ansys. In the experimental work the polymer material  perspex is used in which 9 layers of perspex material are mounted on milling machine bed and machining is done along with work piece material to reduce the vibration and to found out the damping. How this can be analysed in ansys and which models can be used for this. Many layers are stacked one upon the other and damping has to be found out.How this modelling can be done.

contact problem

hi all,

my name is christian, i'm a master degree student in mechanical engineering. i've been doing a swaging  process simulation using MSC.MARC, but i have a problem.when i ran the simulation, there were some node or element that penetrated into the other element and/or rigid body. i tried to change the value of contact tolerance and mesh, but i got the same result (pentrated still happened). what should i do to solve this problem?should i use mesh adaptivity? please help me ^^

Applications of Fracture Mechanics

These notes were prepared when I taught fracture mechanics in 2010, and were updated when I taught the course again in 2014.

Notes on other parts of the course are also online.

Post-Doctoral Position in Nanostructured Solar Cells

The Microelectronics Research Center at the University of Texas at Austin has an immediate opening for a Post Doctoral Researcher in the area of nanostructured solar cells. It is desirable that an applicant have experience and interest in topics related to basics of solar cell design, fabrication and testing. Applicants from related areas such as optoelectronics or nanoelectronics will also be considered provided they have experience in device design, fabrication and testing. A successful candidate must hold a doctorate degree in Engineering, Applied Physics or other related areas.

Post-Doctoral Position in Large Area Nanofabrication of Quantum Dots

The Microelectronics Research Center at the University of Texas at Austin has an immediate opening for a Post Doctoral Researcher in the area of large area nanofabrication of quantum dots. It is desirable that an applicant have experience and interest in topics related to nanolithography, reactive ion etching of deep nanostructures, and nano-scale material characterization. A successful candidate must hold a doctorate degree in Engineering, Applied Physics or related fields.

New idea in fatigue problems

there are two analytical concepts that are very important in fatigue failure.the first one is crack closure and the others is residual stress .the first one is in behind of crack and the other emphasis in the front of crack tip. the question is if we use some devices such as AFM/SEM is it possible we model the energy filed during fatigue process?   if this idea can be investigated the second question can be asked: is there any similarity to model for different loading conditions? 

 

I appreciate if you also put your comment in my idea?
