All things equal with a BPO/DMA cured vinyl ester laminate (.150" thick)60" diameter cylinder with a HDT of 220F:
1. Speed of reaction and ultimate exotherm produced will effect degree of initial cure but also can induce MORE stress into the laminate than a slower cure due to higher shrinkage...
We have an ongoing issue with cracking around nozzle attachments in over the road filament wound tankers. Only see this in sodium hypochlorite service. Appears to be predominate in the high stress areas such as nozzles and to some extent head attachment.
1. Road tankers have very high dynamic...

I have a design using ABAQUS 6.7 and need to find a new engineer continue the project. What do I need from the original designer? Do I just ask for the complete file and then it can be transferred to another designer?
Thanks,
