Multiaxial Fatigue Behavior of Cylinder Head for a Free Piston Linear Engine

摘要: Abstract: This study was presented the assessment of multiaxiai fatigue criteria cylinder head for a free piston linear engine using finite element analysis techniques. The structural solid modeling developed utilizing computer-aided design software. clement and were performed codes. biaxiality to assess fatigue. material parameter Hoffmann-Seeger methods considered modify uniaxial properties. Prediction life, effect stress combination proportional loading condition investigated in this study. It can be seen that correction method gives conservative predicted life as compared loading. materials most prediction with SWT criteria. is also observed more use Signed Tresca von Mises result lie between absolute maximum principal signed results. approach shows quite suitable integration commercial code provide an integrated environment evaluation under general conditions.
