摘要： A method for analyzing fatigue life of an elastomeric component includes a step of conducting a finite element analysis to obtain a base state. A plurality of case vectors are then selected to represent a space of possible loading states that occur within a time-varying load data signal based on measurement of the elastomeric component or on a simulation of multibody dynamics. For at least a portion of the case vectors, a finite element analysis is conducted at a plurality of discrete gridpoints along the case vectors starting at the base state and tracking the case vector. Using an interpolation engine, desired local solution variables for a current state may be interpolated from the finite element analysis at the plurality of discrete gridpoints. A damage calculation may then be calculated based on the desired local solution variables for the current state.

摘要： A testing instrument and method for measuring the intrinsic strength of polymeric materials via cutting includes a pair of mechanical clamps connected at a base to low-friction hinges. The clamps are configured to secure the elongate edges of a polymer specimen, and to periodically load the specimen to a predetermined strain. The load on the specimen while strained is measured with an opening force load sensor. While in the strained condition, the specimen is cut with a highly sharpened blade, and the cutting force also measured by a cutting force load sensor. A cutting energy curve may be plotted from these measurements, from which a cutting energy can further be derived.

摘要： A digital twin system for predicting a residual life of a physical asset includes at least one user computer and at least one server. The user computer has a graphical user interface permitting a user to receive damage event warnings, end of life warnings, and status reports. The server communicates with the user computer and includes an administration subsystem that is in communication with a data source. The administration subsystem includes at least one database. The administration subsystem is configured to receive the physical asset's operating history data transmitted by the data source and store the operating history data into the database. The server further includes a simulator. The simulator is in communication with the administration subsystem and is configured to perform several functions, for example, updating the digital twin and generating residual life predictions.

The clamps are configured to secure the elongate edges of a polymer specimen, and to periodically load the specimen to a predetermined strain. The load on the specimen while strained is measured with an opening force load sensor. While in the strained condition, the specimen is cut with a highly sharpened blade, and the cutting force also measured by a cutting force load sensor. A cutting energy curve may be plotted from these measurements, from which a cutting energy can further be derived. The cutting energy is compared to a control material with a known cutting energy and intrinsic strength. The cutting energy and intrinsic strength being linearly proportional, the cutting energy for the specimen may thereby be determined.

摘要： A system for providing digital twin services for a physical asset from multiple twin providers can have a plurality of provider terminals, an asset owner terminal, and a server. The server can be in communication with the plurality of provider terminals and the asset owner terminal. The server can include a processor, a memory, an administration subsystem, and an operation subsystem. The memory can have a tangible, non-transitory computer readable medium with processor-executable instructions stored thereon. The administration subsystem and the operation subsystem can be configured to perform a variety of digital twin services, including instantiating a new digital twin from a provider, updating the digital twin using incrementation instructions from the twin provider and usage history recorded from a physical asset, and querying the digital twin to produce reports of current life remaining.
