Summary
This study analyzes how openings affect steel ship hull plates under stress. Key parameters like plate thickness and hole shape significantly impact structural integrity and strength.
Area of Science:
- Naval Architecture and Marine Engineering
- Structural Engineering

Purpose of the Study:
- To investigate the influence of various parameters on the ultimate capacity of steel plates with rectangular holes under axial stress.
- To evaluate the impact of plate thickness, opening aspect ratio, number and position of openings, and boundary conditions on plate performance.
- To provide insights for optimizing the structural design of ship hull components with openings.
Main Methods:
- Utilized ANSYS finite element analysis (FEA) for non-linear static structural simulations.
- Investigated the effects of plate thickness, opening aspect ratio, number of openings, opening position, and boundary conditions.
- Compared FEA results with established analytical methods, including Navier solution and Roark's Formulas.
Main Results:
- Quantified the influence of investigated parameters on stress distribution and deformation in steel plates with openings.
- Demonstrated that parameters such as plate thickness and opening aspect ratio significantly affect ultimate capacity.
- Numerical simulations showed good agreement with analytical solutions, validating the FEA approach.
Conclusions:

01:23Stresses under Combined Loadings

When analyzing a bent tube with a circular cross-section subjected to multiple forces, it is crucial to determine the stress distribution in order to maintain structural integrity under varied load conditions.
The process begins by slicing the tube at critical points and analyzing the internal forces and stress components at these sections, focusing on the centroid. Normal stresses, generated by axial forces and bending moments, are either compressive or tensile and vary across the section from...

01:11Distribution of Stresses in a Narrow Rectangular Beam
237
In studying beam stress distribution, examining an elemental section is essential. To determine the average shearing stress on this face, the calculated shear is divided by the surface area. Importantly, shearing stresses on the beam's transverse and horizontal planes mirror each other, indicating a consistent stress distribution along the upper region of the beam. Notably, shearing stresses are absent at the beam's upper and lower surfaces due to the absence of applied forces in these...

01:16Eccentric Axial Loading in a Plane of Symmetry
277
Eccentric axial loading occurs when an axial load is applied away from the centroidal axis of a structural member. This scenario is common in engineering, where structural elements may not be directly aligned due to various design or functional requirements.

01:14Shearing Stresses in a Beam: Problem Solving
296
A cantilever beam with a rectangular cross-section under distributed and point loads experiences shearing stresses. The analysis begins by identifying the loads acting on the beam. Then, the reactions at the beam's fixed end are calculated using equilibrium equations. The vertical reaction is a combination of the distributed and point loads, while the moment reaction is the sum of their moments. The shear force distribution along the beam, resulting from these loads, is established by...

01:15Relation between Poisson's ratio, Modulus of Elasticity and Modulus of Rigidity
322
Deformation occurs in axial and transverse directions when an axial load is applied to a slender bar. This deformation impacts the cubic element within the bar, transforming it into either a rectangular parallelepiped or a rhombus, contingent on its orientation. This transformation process induces shearing strain. Axial loading elicits both shearing and normal strains. Applying an axial load instigates equal normal and shearing stresses on elements oriented at a 45° angle to the load axis.

01:18Saint-Venant's Principle
820
The principle of Saint-Venant postulates that the stress distribution within a structural member does not rely on the precise method of load application except in the vicinity of the load application points. Consider a scenario where loads are centrally applied on two plates. In this case, the plates move toward each other without any rotation. This movement causes the member to contract in length and expand in width and thickness. Uniform deformation across all elements and maintaining...
