During impact in SHPB tests, an increase in temperature was observed. The dissipated energy affects the viscoelastic behavior of composites especially when the released temperature attains the Tg of the matrix. Does anyone know any high speed infrared detector (camera) which is able to monitor temperature dissipation during impact tests or quantified the dissipated energy due to damage?
Your help will be very appreciated.
JE PENSE QUE L AUGMENTATION DE LA TEMPERATURE N AFFECTE PAS VOS RESULTATS EXPERIMENTAUX
LES MOYENS CONVENTIONNELS ONT TOUJOURS UNE CERTAINE INERTIE
JE PENSE QU IL FAUT ADDRESSER CETTE QUESTION A MR DEMAGH ET J ESSAIE DE LE CONTACTER
We have got in some experiments that dynamic properties such as maximum stress and strain at maximum stress are strain rate dependent until a threshold. Among factors,the threshold effect was attributed by other researchers to the increase of temperature during impact tests.
You are right Katakam. I'm speaking about composites with polymer matrix.
Dear Larbi
we have in our optics laboratory a pyrometer (laser). the measure with no contact
in the moment i can't give more details, but i hope to ask for it Mme Aicha Medjahed
