    摘要: Systems and methods for modeling stress intensity solutions of integrally stiffened panels are disclosed. In one embodiment, a method includes serving a process over the internet. The process includes taking a problem definition, automatically forming a finite element model at least partially based on the problem definition, automatically verifying a suitability condition of the finite element model, automatically solving a computational solution using the finite element model and automatically validating the computational solution. In one aspect, providing a problem definition includes at least one of providing a geometry definition, providing a crack definition, and providing load and constraint definition.

    摘要: Systems and methods for analyzing structural test data are disclosed. In one embodiment, a method includes applying a sequence of loads to a test article, receiving raw test data indicative of the applied loads from at least one sensor operatively associated with the test article, receiving predicted test data indicative of the predicted loads on the test article, filtering out invalid test data, cycle counting to pair loads in the test data, performing a first fatigue damage computation based on the raw test data, performing a second fatigue damage computation based on the predicted test data, and comparing the first and second fatigue damage computations. The filtering, cycle counting, and performing of the first and second fatigue damage computations, and the comparison of the first and second fatigue damage computations, may be performed simultaneously using a spreadsheet program.
