The piston is the crucial part of the internal combustion engine. The  objectives  of  this  project  are  to  predict  fatigue  life  of  piston  for  four  stroke engine  using  strain-life method,  to  identify  the  critical  locations,  to  investigate  the effect  of mean  stress  and  to  optimize  the  component material.  The structural and finite element modeling has been performed using a computer aided design and finite element analysis software package.  The  finite  element  model  of  component  then analyzed  using  the  Strain  method  approach.  Finally, the stress-strain state of component obtained previously will be use as input for the fatigue life. The effected mean stress and materials optimize was also too investigated. The failure of piston can result in devastating damage to the engine including all the components from a tiny screw till a huge belting system. Life of piston needs to be improved to prevent from any unpleasant problems. The  results of  the analysis showed  that  there are no serious  failure  occurs  at  the  part  of  the  piston.  However  it  is  observed  that  the minimum  predicted  life  at  the  critical  location  is  102.38e-7 under variable  amplitude loading for strain-life approach. The optimization results showed 7075 T6 aluminum alloy that is the most superior material among the others. -Author- 0aFatigue testing machines 0aFinite element method 0aPistons  00104071a20000b20000d2019-09-04l0oTA418.38 .M39 2008 rs Bc.p0000038118r2019-09-04 00:00:00t1w2019-09-04yPSM  00104071a20000b20000d2019-09-04l0oCD 3412 | TA418.38 .M39 2008 rs Bc.p0000038119r2019-09-04 00:00:00t1w2019-09-04yPSM  aVIRTUA40c1209d1215  aVTLSSORT0080*0200*0400*0900*1000*2450*2460*2600*3000*5020*5200*6500*6501*6502*9992
