Working with Qualitative Variablessses. The structural designer needs to know the hull structure load features, as accurately as possible: direction of the working load, frequency of occurrence, distribution pattern on the hull structure and behavior in the time domain, etc. The first design step is to assume exact loads acting on t

From the Sample to the Population hull structure has been planned originally by the designer in such a way that the structure can effectively resist the presumed maximum load, which is estimated from previous experience of failure modes of damage. Therefore, once damage occurs in the structure, it indicates the following facts:

Definition of a General Model: Examplelso in the design of most industrial products and even in non-structural fields. FEM can be used for a wide variety of problems in linear and nonlinear solid mechanics, dynamics, and ships’ structural stability problems, in accordance with the development of computer technology and its popularizatio

Definition of a General Model: Exampleendure the lateral forces such as water pressure as well as in-plane loads. When the forces are imposed, the stress distribution in the plates and the stiffeners is complex as shown in Fig. 1.1.1. The longitudinal stress in the attached plate will be a maximum at the connection line to the stiffener

Tim Nugent,David Jones,Sikander Hayatf tankers, appeared. Initially the web plate of the transverse ring buckled under water pressure tests. Then cracks appeared at slots where the load is transmitted to the girder’s web plate from the longitudinal frames.

Tim Nugent,David Jones,Sikander Hayatlar is a very effectivestructural member, for example 40 cm. sectional area of mild steel can support 1000 kN force (σ = 250MPa). Considering that the pillar sometimes supports tension, attention should be paid to the connection at both ends of the pillar.

The strength of such plates is most important since many kinds of load act directly on the plates, especially water pressure and longitudinal bending. The strength of plates is usually taken as a plane rectangular plate having uniform thickness. The boundari
