摘要： This invention provides an information processing apparatus for fabricating a desired three-dimensional fabricated object by suppressing shrinkage of a fabricated object caused by a temperature drop in a laminated portion at a fabricating time of the three-dimensional fabricated object. This information processing apparatus includes an acquirer that acquires laminating and fabricating data of a three-dimensional fabricating model, and a data generator that generates laminating and fabricating data of a three-dimensional fabricating model added, when a width in a predetermined direction on a laminating surface of a fabricated object is equal to or larger than a threshold, with a shrinkage suppression structure model for suppressing shrinkage after laminating and fabricating, in the predetermined direction. The shrinkage suppression structure model is a plate-like structure model extending in the predetermined direction and having a length which can suppress shrinkage after laminating and fabricating.

摘要： A method to utilize the results from a series of FEM models to develop a master derivative of compliance curve. The use of the unique master curve resolves test data variability issues caused by fitting the compliance curve individually. The analytically derived derivative of compliance curve eliminates the needs to take the derivative of compliance and therefore the derivative computation error no longer exists. By applying the existing solution and the solution as disclosed and claimed herein to the same set of raw test data, it is found that data scatter is significantly reduced.

摘要： A method for analyzing a structure includes processing nondestructive inspection (NDI) data (112) for a multi-layer structure to define areas of inconsistency at an internal layer or an interface between adjacent layers. The method includes mapping (106) the areas of inconsistency to finite elements of a finite element model (114) of a nominal of the structure. These finite elements are thereby identified as affected finite elements and include finite elements for the affected internal layer or interface. The method includes producing a reconstructed finite element model (116) of the affected structure from the nominal finite element model (114), and a modified property or state value assigned to respective element datasets of the affected finite elements. The method includes performing a finite element method (FEM) failure analysis (110) of the reconstructed finite element model (116) under a load, which indicates an extent of residual integrity of the affected structure.

摘要： The invention relates to a method for designing the wall thickness of permanently statically and/or dynamically loaded components, wherein the components are produced from a fiber-reinforced polymer material. In a first step, the orientation of the fibers in fiber-reinforced plastic and the location of the joint lines in the component are determined by a first simulation calculation. A utilization factor of the strength of the component is calculated in a second simulation calculation. The wall thickness of the component is adapted to the result of the second simulation calculation, and the previous steps are repeated if the wall thickness is subjected to change. The invention further relates to a component made of a fiber-reinforced polymer material having a wall thickness designed by the method according to the invention.

摘要： A computer implemented method, apparatus, and computer usable program code for providing ply lay-up data for a composite part. A designation of a location is received for the composite part in a three dimensional object from a requester. A three dimensional model is opened in which the composite part is located. The ply lay-up data is extracted for a section within the composite part within the three dimensional model to form extracted ply lay-up data for the section. An output file is created containing a two dimensional drawing for the section with the ply lay-up data identifying a ply stacking sequence, an orientation of each ply in the ply stacking sequence, and a material for the each ply in the ply stacking sequence. The output file is returned to the requester.
