Abstract: A preferential bend structure may have a first face and an opposing second face. The preferential bend structure may comprise at least a base layer and an auxiliary layer, wherein a first deforming force applied to the first face results in a first deflection and a second deforming force applied to the second face results in a second deflection which is equal to the first deflection, and wherein the second deforming force is not equal to the first deforming force.

Abstract: A method of quantitatively analyzing results of a model. At least one image of a model is generated in a post-processor. A calibration mechanism of known dimensions is generated in the post-processor. The calibration mechanism is read into an analysis software. The image is read into the analysis software. The image from the post-processor is analyzed in the analysis software quantitatively using the calibration mechanism.

Abstract: A computer method for simulating motion of at least a portion of a virtual body is disclosed. The method comprises the steps of: providing a surfaced body model; capturing or computing motion data for an external surface of the surfaced body; dividing the body model into at least two volumes, one of the volumes comprising at least a portion of the external surface of the surfaced body and being a deformable volume, and one of the volumes being a prescribed motion volume, the two volumes defining an interfacial surface; moving the external surface of the surfaced body according to the motion data while computing motion of the interfacial surface; and, simulating motion of the portion of a body by driving motion of the interfacial surface through the computed motion to provide an accurately positioned moving deformable surface that can be used in garment design.

Abstract: A virtual model capable of simulating physical deformation of at least a portion of a body. The model comprises at least two computer-generated volumes that together define an external surface and an interfacial surface, one of the computer-generated volumes being a deformable volume and one of the computer-generated volumes being a prescribed motion volume. At least a portion of the interfacial surface has a prescribed motion associated therewith.

Abstract: A virtual model capable of simulating physical deformation of at least a portion of a product to be worn on a body. The portion comprises a longitudinal fold or pleat and model comprises at least two elements. The two elements are joined along a common boundary of nodes, and the elements offer substantially no bending resistance at the boundary of common nodes.

Abstract: An absorbent article providing improved body fit. The absorbent article includes an extensible fluid permeable facing layer and a first absorbent layer joined to the facing layer. The first absorbent layer includes zones of extensibility. Each zone of extensibility is a region of the first absorbent layer of relatively higher extensibility than regions of first absorbent layer adjacent to the zone of extensibility. A liquid impermeable backsheet is joined to the facing layer at the periphery. The liquid impermeable backsheet has a garment facing surface. A fastening means is disposed on at least a portion of the garment facing surface of the liquid impermeable backsheet. The fastening means defines attachment zones. At least a portion of the first absorbent layer is decoupled from the attachment zones of the fluid impermeable backsheet.
