Abstract
A method, apparatus and computer program product is disclosed for determining the strain induced at a selected point in a stiffened panel structure in response to a load, taking into account one or more out of plane (OOP) effects.
Claims36
A method for determining the strain induced at a selected point in a stiffened panel structure in response to a load, taking into account one or more out of plane (OOP) effects, said method comprising the steps of:
- defining a model of a stiffened panel structure;
- determining an analysis point in said stiffened panel structure;
- selecting an input load for said stiffened panel;
- inputting data defining an out of plane (OOP) effect;
- modeling a plurality of said stiffened panel structures as a continuous beam and calculating the boundary conditions of a selected one of said stiffened panel structures within said continuous beam model in response to said input load and taking into account said OOP effect;
- modeling a single stiffened panel structure as local beam model;
- and
- calculating the strain at said analysis point in said local beam model taking into account said boundary conditions calculated from said continuous beam model and further taking into account said OOP effect.
Apparatus for determining the strain induced at a selected point in a stiffened panel structure in response to a load, taking into account one or more out of plane (OOP) effects, said apparatus being operable to:
- define a model of a stiffened panel structure;
- determine an analysis point in said stiffened panel structure;
- select an input load for said stiffened panel;
- input data defining an out of plane (OOP) effect;
- model a plurality of said stiffened panel structures as a continuous beam and calculate the boundary conditions of a selected one of said stiffened panel structures within said continuous beam model in response to said input load and taking into account said OOP effect;
- model a single stiffened panel structure as local beam model;
- and
- calculate the strain at said analysis point in said local beam model taking into account said boundary conditions calculated from said continuous beam model and further taking into account said OOP effect.
