greeting everyone,<\/p>\n
i’m a final year students of mechanical engineering and currently working on developing my samples via ANSYS WORKBENCH. i’m currently setting up a proper methodology for test with standard ASTM D1599-99 which is a hydrostatic pressure test for thermoplastic material. <\/p>\n
summary of experiment : a 1m pvc pipe with 3mm thickness and 20mm hole in the middle was repaired with fiber reinforced polymer composite. The fibers will varies more than 5 type while the resin is polyurethane thermoplastic (poly silicate isocyante – WILLKAT). the repaired pipe was put under hydrostatic pressure from 0 to 15MPa and usually the pipe will burst.<\/p>\n
the pipe was designed in design modeler but for the testing part i was a bit confuse. i already applied the pipe with both hydrostatic pressure and pressure. my concern is if i want to build exact test in simulation, which applied pressure are more suitable? hydrostatic pressure does not allowed me to put the exact applied pressure however i used it bcause my project was based on hydrostatic pressure. while pressure allowed me to applied desired pressure but i’m affaid it will include atmosphere pressure. <\/p>\n
result that i obtain from both pressure in simulation:
hydrostatic pressure : run well but the maximum stress and strain are not same with the experiment
pressure : ANSYS state the step size are too small and few random hole was appear on the pipe surface after pressure applied. i dont know if this mean the pipe had burst or else).<\/p>\n
can somebody help me ??<\/p>\n
