The Naval Research Laboratory (NRL) is seeking information from potential sources capable of developing custom software for a phenomenological model relating the crack growth rate to stress intensity factors. The project involves the development of a state-of-the-art modeling and generation framework for crack propagation datasets using model encoding and stochastic methods. The contractor will be required to conduct research in three major task areas: implementation of a statistical calibration method for HS model parameters, implementation of sampling algorithms and verification and validation tasks, and application of algorithms and models to datasets provided by NRL. • The contractor must have experience in materials modeling, statistical methods, and uncertainty quantification. • The contractor must have a PhD in computational mechanics and expertise in developing and deploying algorithms for Naval applications. • The contractor must provide a capability statement that includes company name and address, point of contact, telephone number and email address, DUNS number, and business size/socioeconomic categories. • The contractor must provide a description of how the proposed product will meet or exceed each of the specifications. • The contractor must provide a product brochure and highlight the areas that meet or exceed specifications.
