摘要：

An improved analytical model for the axisymmetric stress state of an adhesive joint of two cylindrical shells is proposed. The adhesive layer acts in shear and cleavage. It is assumed that the tangential stresses vary linearly across the thickness of the adhesive layer. The two-parameter Vlasov-Pasternak model of an elastic foundation is used to describe the normal stresses in the adhesive. The approach proposed makes it possible to satisfy boundary conditions at the load-free butt of the adhesive layer and to describe the stress state of adhesive with a high accuracy. The closed-form solution is obtained. A model problem is also solved.

[38] Q: We fabricate a lot of carbon steel pipes. Occasionally we get a job that uses carbon steel pipes lined with stainless steel. Sometimes the liner is 304L, sometimes 316L. Since the pipes have a relatively small diameter, they can only be welded from the outside. In preparing the joint, we peel back the carbon steel to expose the stainless in the root area, then weld the root and one or two more layers with gas tungsten arc welding (GTAW) using 309L (for a 304L liner) or 309LMo (for a 316L liner) filler metal, and argon backing gas. We finish the joint with 309L or 309LMo covered electrodes or flux core. This seems like a waste of expensive filler metal. After we get the stainless steel root pass in place, why not finish with carbon steel filler metal?
