PA for offshore pipes

[Ausberto]

Hi Dr Jorgen


I am investigating a damping properties of PA11
I need a information of complex module in frequency domain
and shift factor for time temperature superposition
I assuming
1- small starin
2-LVE behavior
3-Low frequencies 0.01 to 10 Htz

I have a lVE prony serie for t> 2 in T=23 oC, but my program need information in t<2 seg, for this reason the frequncy domain is more eficient
but i am search hardly this information buy i could[t find

If you have any informatio about G(w) an G``(w) in low frequenies of PA11, PA12, PVF2
for offshore aplication i am gratefuly for you help

Thank
Ausberto

I am afraid that I dont' have the experimental data that you are looking for. I suggest that you run some Dynamic Mechanical Analysis (DMA) experiments to determine the frequency response. DMA is a quick and easy test that should give you exactly what you are looking for.
