Hi everybody

I am translating a technical French paper. what can i use as the english equivalent of "pouvoir comburivore"? 

Thanks in advance

Dear eveyone,

I need to know the formula or expression to calculate the flexural rigidity (D) of RC Slab reiforced with steel bars. I know that for plain concrete, D can be taken as Et3/12(1-v2). However, I have no idea what is D when steel bars are added to slab. I really appreciate for any kind help. Thanks

Hellow,everyone here:

      Anyone knows  the fatigue limit and the long-crack threshold of Aluminum 2024-T3?Thanks very much.

Dear all,

Folks,

I'm embarking on a project to build a modified copy of a DIY 3D printer.  See http://reprap.org/wiki/WebHome to get a rough idea.  In my case, I have my own lathe and milling machine, so I can fabricate more substantial components, e.g., by machining aluminum.  I also have larger stepper motors, some 3/8" precision rod and linear bearings that I can use. 

I need to model viscoelastic behavior of polymer. I have storage modulus and loss modulus data as a function of temperature. I have found to determine the Prony series coefficients Ansys need shear and bulk modulus as a function of time-temperature. Does it mean complex shear moduls which can be calculated from storage and loss modulus. Can anyone advise me how I can use my data to calculate Prony series coefficients using Ansys?

A number of 3 year PhD-Student positions in the areas of mechanical engineering, process engineering and applied mathematics is available in the Post-Graduate School "Micro-Macro-Interactions in Structured Media and Particle Systems", Otto-von-Guericke-University Magdeburg, Germany.

A recent discussion at iMechanica following my last post here [^] leads to this post. The context of that discussion is assumed here.

I present here three sample problems, thought of almost at random, just to see how the suggestions made by Jaydeep in the above post work out.
