Hello,

 

I have to perform a thermo-mechanical simulation in Ansys WB and I have to provide the cte of a material.

I have few experience with thermo-mechanical simulation.

I have got a document with the material properties of this material; there I have the Tg (glass transition temperature)

and two coefficients: cte1 (below Tg) and cte2 (above Tg).

 

-->  How should I calculate the CTE for a temperature range (e.g. -50 < Tg < 300) ?   <---

In this paper, we investigate the formation of band-gaps and localisation phenomena in an elastic strip nearly disintegrated by an array of transverse cracks. We analyse the eigenfrequencies of finite, strongly damaged, elongated solids with reference to the propagation bands of an infinite strip with a periodic damage.

Can an elastic rod attain self-encapsulation when loaded transversally at midspan?

The elastic rod assumes the form of a liquid drop at self-encapsulation!
