Thickness calculation for Shell portion: ASME BPV Code Sec. VIII D.1

Assumptions:  Weld efficiency factor (E) = 1.00  Design temperature = 28°C  F.O.S = 3, thus S (maximum allowable stress) = 215 / 3 = 71.66 MPa

Physics Requirements ?? Thickness (barrel section) of < = 0.5 radiation lengths

Summary and future work

  • Preliminary calculation and simulations are carried out for pressure vessel of TPC
  • At 40 mm shell thickness; Von mises stress and displacement is evaluated by

simulations

  • With out ribs, the maximum Von mises stress on vessel is about 100 MPa.
  • With three ribs, Von mises stress on vessel reduces to about 85 Mpa
  • Above level of Von Mises stress are lower than the Yield strength of the

designated Aluminum, i.e. 215 MPa
