Hello,<\/p>\n
I am currently simulating a heat sink with a fluid structure interaction. I am comparing an aluminum nitride heat sink to a copper heat sink. Essentially, I have simulated a fluent case and linked it to a tranisent structural case. Water flows between the heat sink microchannels, and the heat sink itself is subjected to fluctuating heat fluxes over time. That being said, I am not certain as to whether many creep life models are applicable, since my simulation is not steady state. I also am unsure as to how I would go about assigning creep life constants for many of the creep life models. <\/p>\n
I believe it is more appropriate to consider a fatigue life model, since that pertains to fluctuating loads. However, I am also unsure about how I would go about setting up that scenario for simulations either.<\/p>\n
Any help or insight would be greatly appreciated<\/p>\n","protected":false},"template":"","class_list":["post-368984","topic","type-topic","status-closed","hentry","topic-tag-creep-analysis-1","topic-tag-creep-constants","topic-tag-creep-simulation-1","topic-tag-fatigue","topic-tag-fatigue-analysis","topic-tag-fatiguefailure-1","topic-tag-fatigue-life"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
