"The progressive modeling may include, for example, simulating ballistic impact, inconsistencies, penetration, matrix cracks, delamination, fiber tension shear, fiber compression, fiber crush, and/or other undesired effects that may occur for a composite structure and/or material." "For example, in some advantageous embodiments, more than one level of simulations and/or analysis may be performed. For example, a simulation of a platform, such as an aircraft, may be performed. Thereafter, an additional identification of a portion of the aircraft may be selected for analysis or further simulation. For example, stringers in a portion of a fuselage may be selected for the additional analysis or simulation. Characteristics for stringers in the fuselage may be identified from the simulation already performed or from additional simulations" * | by applicant | - DAVIDSON ET AL., "An Analytical Crack-Tip Element for Layered Elastic Structures", ASME JOURNAL OF APPLIED MECHANICS, (199506), vol. 62, pages 294 - 305 | - "Energy Release Rate Determination for Edge Delamination Under Combined In-Plane, Bending and Hygrothermal Loading.
