Dear all,

I am using Abaqus to model concrete as an elastic material. However, the failure criteria available in the software is only for 2D elements and are dominated by a maximum normal stress (fail stress option) or normal strain (fail strain option) value.

I was wondering if anyone would know how to model concrete as an elastic material following "theory of elasticity" and failing by a maximum TENSILE strain value in any of the three directions given a material's point.

It would also be perfect if deleting elemnts option can be used in this case.

Lithium-assisted plastic deformation of silicon electrodes in lithium-ion batteries: a first-principles theoretical study

lithium-ion battery

Silicon can host a large amount of lithium, making it a promising electrode for high-capacity lithium-ion batteries.  Recent experiments indicate that silicon experiences large plastic deformation upon Li absorption, which can significantly decrease the stresses induced by lithiation and thus mitigate fracture failure of electrodes. These issues become especially relevant in nanostructured electrodes with confined geometries.

Generation of Sound (or Ultrasound) Waves & Resonance

Submitted by Babaei on

Hi,

 

I have a question and would be grateful if you could drop me some lines for it: 

1- Is sound (or ultrasound) is ONLY generated when a structure is vibrating at its resonance frequency?   

2- If the answer to the above question is YES, is sound (or ultrasound) generated at all resonance frequencies or just some of them depending on the amplitude of the vibration. 

 

Thank you,

Babaei
