METHOD AND TOOL FOR MODELING CHANGES IN SOLID MATERIALS CAUSED BY GALVANIC OR CHEMICAL INTERACTIONS

Abstract:

A method including receiving environmental data, sensor data, and a multi-state model are received for an object. The object includes a first material and a second material that galvanically or chemically interacts with the first material. Each of distinct galvanic or chemical state of the object represents a corresponding different equation applicable to a corresponding specific galvanic or chemical interaction between the first and second materials. A stochastic optimization operation is performed on the multi-state model until convergence on candidate sets of galvanic or chemical material change rates for the distinct galvanic or chemical states of the object. A correlation model is generated for a surrogate parameter for the second physical parameters by correlating the environmental data to the sensor data using the candidate sets of galvanic or chemical material change rates. An aircraft design is generated using the correlation model.
