Abstract: Examples are disclosed that relate to computer-predicting behavior of foreign object debris (FOD) in a machine. In one example, a geometric computer model of the machine is recognized. FOD initial conditions within the geometric computer model of the machine are recognized. A movement schedule for the geometric computer model of the machine is recognized. A movement trajectory of a FOD from a starting position consistent with the FOD initial conditions throughout the geometric computer model of the machine is simulated based at least on the movement schedule for the geometric computer model of the machine. Simulation data detailing a likelihood that the FOD will come to rest at a location within the geometric computer model of the machine based on the simulated movement trajectory is output.

Abstract: A method for certifying a design of a liquid container onboard a vehicle for manufacture of the liquid container is provided. The method includes generating a computer geometric model of the liquid container according to the design, and executable code to reproduce dynamics and operational parameters of the vehicle, with the dynamics of the vehicle including dynamics during a vehicle maneuver that is selectable from a database of vehicle dynamics for a plurality of vehicle maneuvers. The method includes executing a simulating application to perform a simulation of liquid sloshing in the liquid container onboard the vehicle is performed subject to the dynamics and operational parameters, and iterate the simulation to refine a prediction of loads and stresses on the liquid container from the simulation produced thereby. Locations within the liquid container more vulnerable to fatigue-risk are identified based on the prediction, and output for certification of the design.

Abstract: Systems and methods are provided for composite part design. One embodiment is a method for selectively analyzing feasibility of optimizing fiber orientations for layers of a multi-layer composite part subdivided into panels that each comprise a fraction of an area of the composite part. The method includes identifying stacking sequence rules that constrain the composition of sublaminates that comprise consecutively stacked layers utilized during optimization, for each panel of the composite part, analyzing the panel by identifying ply counts that constrain a number of plies at the panel, selecting a number of sublaminates to utilize during optimization of the panel, calculating ply count ranges for a laminate, based on the number of sublaminates and the stacking sequence rules, and determining whether the ply counts for the panel comply with the ply count ranges for the laminates.
