AB  - The characterization of thermal ratcheting behavior of high density polyethylene 
      (HDPE) material coupled with compressive creep is presented. The research 
      explores the adverse influence of thermal cycling on HDPE material properties 
      under the effect of compressive load, number of thermal cycles, creep time 
      period, and thermal ratcheting temperature range. The compressive creep analysis 
      of HDPE shows that the magnitude of creep strain increases with increase in 
      magnitude of applied load and temperature, respectively. The creep strain value 
      increased by 7 and 28 times between least and maximum applied temperature and 
      load conditions, respectively. The creep modulus decreases with increase in 
      compressive load and temperature conditions. The cumulative deformation is 
      evident in the HDPE material, causing a reduction in the thickness of the sample 
      under thermal ratcheting. The loss of thickness increases with increase in the 
      number of thermal cycles, while showing no sign of saturation. The thermal 
      ratcheting strain (TRS) is influenced dominantly by the applied load condition. 
      In addition, the TRS decreases with increase in creep time period, which is cited 
      to the extended damage induced due creep. The results highlight the need for 
      improved design standard with inclusion of thermal ratcheting phenomenon for HDPE 
      structures particularly HDPE bolted flange joint.
