Glad it was helpful!

[@bhoominathan1981]

can we ensure the cross-linking of thermosetting polymers from the data obtained from DMA

[@METTLERTOLEDOLaboratory]

Hi, The effects or properties of crosslinking of thermosets can be investigated by DMA.

[@Mike71857]

Thank you, very useful for my new job.

[@METTLERTOLEDOLaboratory]

Great to hear!

[@aniawo5119]

Very useful. Thank you. Not sure whether I fully understand why material's behaviour at high frequency is equated to behaviour at low temperature and vice versa. Could somebody elucidate? Thanks

[@cheezwiz7]

From my understanding:Viscoelastic properties are largely based on response time. The response time is forcibly shortened at high frequencies due to less time between cycles, while at lower temperatures the response time is shortened because cold temperatures slow the "flow" of molecular chains.

cheezwiz7 Thank you. Makes sense.

[@miottochiesa1989]

thanks this video helped me a lot! excellent quality! thanks!

[@METTLERTOLEDOLaboratory]

You're welcome, I am glad it helped!

[@Mech.Masters]

How is Storage modulus (E') and Elastic Modulus (E'') calculated by the machine performing DMA without the value of delta?

[@cheezwiz7]

My guess would be:Delta is the phase shift between the generated stress vs time and strain vs time sin waves. The DMA can calculate this directly because it measures the displacement vs time and the load vs time which can then be used with the cross sectional area to get both sin curves.

kzbin.info/www/bejne/rXmWe2d6ebaKpMU Can anybody explain how force can be negative (the part of sin wave below dashed line)? What does it mean?

[@jasongarfitt1147]

The sign of the applied force is related to the direction to which the force is being applied. If a force acting up is positive then a force acting down will be considered negative.
