HyperSizer Composite & Laminate Analysis Software
HyperSizer is a composite material analysis software providing stress analysis and preliminary structural design for weight reduction, system level trade studies, and part sizing including sizing stiffened panel cross-sectional dimensions, material selection, and optimum composite layup stacking. HyperSizer performs detailed failure analyses and reporting as a post process to a loads finite element model (FEM).
It is an enterprise tool used by both designers and stress analysts from early concept to final design.
For over a decade, HyperSizer has significantly reduced weight on major aerospace programs with rapid analysis and composite optimization. Originally developed at NASA, it now greatly enhanced and supported as a commercial product worldwide. HyperSizer is not CAD and is not finite element analysis (FEA).
Software
HyperSizer is a software system for management of all data associated with the structural analysis and test data of a major aircraft program. Multiple databases can be setup, with each database able to contain hundreds of variations of an airframe configuration (i.e. different FEMs), material properties, panel and beam concepts, dimensions, and loads. This approach provides apples-to-apples weight prediction comparisons, and a guaranteed store of all margins-of-safety for every configuration. The database also provides an organized and efficient means to capture essential data related to a project with a guaranteed ability to immediately locate and retrieve historical data. Stress reports can be generated at the click of a button at any time documenting current status of a project, indicating critical margins, critical load cases, and critical structural parts.
Analyses
HyperSizer performs hundreds of different analyses such as panel buckling, crippling, beam-column, bonded and bolted joint, composite strength to damage initiation and damage tolerance criteria, etc. for the entire vehicle from engine nacelles to airframe surface panels and substructure. The figure illustrates how HyperSizer imports a FEM and manages all data associated with a configuration. Wing spars and ribs can consider a range of materials and panel concepts that are different than the subset of user determined design options for the wing skins and fuselage body. HyperSizer also analyses and optimizes internal beams such as spar caps and many other open and closed shapes. A primary foundational capability of HyperSizer is to accurately analyze any panel concept without the need to discretely mesh with finite elements the shape of the stiffeners or their spacing. This permits tremendous flexibility and rapid turn around of trades with different panel concepts all from the same coarsely meshed FEM.
Progressive Design Process
The HyperSizer Progressive Design Process consists of three activities. All three activities can interact with each other throughout design maturation. HyperSizer provides unique automation and integration capabilities to each of these design activities.
A funneling process performed in stages to target an optimum design. Innovative ack to the drawing board concepts are proposed, evaluated, and filtered out for the next stage of the design maturation process.
An incremental process of including more computationally demanding analysis solutions starting with damage initiation, tracking the progression of failure, and ending with the resulting residual strength at ultimate failure.
An incremental process of including more design detail, such as bonded and bolted joints, ply drop-offs, etc. for both optimization and analysis.
