Moreover the shapes and details are highly standardised and well proven by previous service data and near full-size specimen tests. Weight as such is not critical. The pressure to economise, though laudable within limits, is aggravated by the

The fuselage was treated as a pressure vessel under repeated loading since it was blown to a pressure of about 0.9 bar when the outside pressure was approximately 0.16 bar. Because there was some unc

Klaus Bichler,Ralf Krohn,Peter PhilippiStress concentrations due to changes of shape arise in most designs. An awareness of the severity of such concentrations is helpful in making design decisions. It is unrealistic to say that all corners must be avoided. We must accept that there will be stress-raisers, for good reasons.

When we consider tethering a weather balloon, dredging samples from the sea bed or drilling deep holes, we need to consider tailoring the rope or drill pipe to the duty in more detail.

Introduction, need the ability to select efficient and safe structural solutions for a given duty. If we merely study analysis of standard cases we may fail to develop either the creative aspect or the knack of spotting weaknesses before they arise in the real object. This point is well illustrated by figure 1.1
