Given the versatility of the polynomial solutions advocated, the method appears well suited for complicated thermal scenarios...

...-stresses help to offset any tensile components generated by the internal pressure on the ID. Preliminary calculations also investigated the influence of these factors when a crack was introduced at the interface of the coating and substrate.

Using this simplification, the model utilized uniform a time-dependen by the propella rifling geomet maximum circu when compared...

.... For the two geometries explored (thick-walled cylinder under an internal transient with external convection and a slab with one adiabatic surface), excellent agreement was seen with various test cases for histories based on either temperature or strain. However, the strain-based solutions may be preferable...

... 24 07 2009 The object of this study is to determine the short-term burst pressure of metal cylinders under short-term dynamic loading conditions. The finite element method via the use of the LS-DYNA code is used to carry out the study. The influence of the geometric parameters diameter...

To help offset these limitations and at the same time solve for the useful case of a thick-walled cylinder exposed to thermal loading on the ID, the inverse problem was solved using a least-squares determination of polynomial coefficients based...
