摘要： A method (100) for predicting distortion of a sheet metal during a sheet forming process to form the sheet metal into a part. The method (100) of the present invention is for use with a computer including memory and sheet forming tools. The method (100) comprises applying (104-116) the radial return method to compute the total stress for the anisotropic hardening rule of Mroz. The method (100) of the present invention does not divide a given strain increment into hundreds of subintervals as long as the movement of the center of the active yield surface is along a fixed path. If a break occurs, the given strain increment is divided into a few segments (110).

摘要： The stamping of a metal sheet within a stamping die is simulated. The die includes a drawbead running perpendicular to a draw direction. A plurality of successive states are generated for iteratively representing the metal sheet from a blank shape to a final stamped shape. The drawbead is represented as a two-dimensional flat band within a model of the stamping die. Forces acting on the metal sheet are calculated at each successive state to define a next successive state. The calculating step includes a restraining force of the drawbead acting on the metal sheet calculated in response to a predetermined function of a length of the metal sheet engaged in the flat band in respective states. The particular width and location of the flat band achieve improved accuracy of estimating the restraining force.

摘要： In one or more embodiments, a weldability of a stack-up for use in vehicle part production may be determined. The determination may include receiving general stack-up information, welding standards data for forming a stack-up, and one or more inputs defining one or more stack-up design variables. Additionally, standardized stack-up information may be generated based on the general stack-up information, the one or more design variables, and the welding standards data. Furthermore, historical welding data may be received for predicting a weldability of the stack-up. Predictive logic may be applied to the standardized stack-up information based on the historical welding data to obtain one or more weldability predictions for the stack-up. The one or more weldability predictions may be transmitted for use in vehicle part production.

摘要： A computer-implemented method for recommending one or more materials used in designing and manufacturing parts may include receiving data from at least three data sources. The data sources may include a sourcing, manufacturing, and design data source. The data source data may be standardized to obtain a collection of data including a dataset of materials for consideration in recommending one or more materials for use in one or more parts. The method may also include receiving optimization metrics and constraints for the dataset of materials. Optimization values for each material based on the dataset of materials and the one or more optimization metrics may be determined. An optimization algorithm on each material may be performed based at least on the optimization values and the constraints to obtain one or more recommended materials from the dataset of materials for use in a design of one or more parts.
