Stress state of a two-layered cylindrical shell caused by assembly of cowlings with deviations from circular shape

  • Published:
Soviet Applied Mechanics Aims and scope

Conclusion

In building up cowlings with initial deviations from the circular shape significant bending occurs (the greatest bending stress on the inner surface is 177 MPa and on the outer surface is 118 MPa; these values are respectively, 157% and 104% of the membrane stresses). The higher harmonics of the initial deviations can here yield a noticeable contribution to the total stress state. Taking account of the geometric nonlinearity results in nonessential corrections in the values of the stresses.
