ESAComp is a software for analysis and design of composites. Its scope ranges from conceptual and preliminary design of layered composite structures to advanced analyses that are applicable for the final verification of a design.

ESAComp for Automotive Use Case ESAComp is software for analysis and design of composites. Its scope ranges from conceptual and preliminary design of layered composite structures to advanced analyses that are applicable to the final verification of a design. Read More
ESAComp has a vast set of analysis capabilities for solid/sandwich laminates and for micromechanical analyses. It further includes analysis tools for structural elements: flat and curved panels, stiffened panels, beams and columns, cylinders, bonded and mechanical joints. ESAComp is a stand-alone software tool, but thanks to its ability to interface with widely used finite element software packages ESAComp fits seamlessly into design processes.
"Today the bi-directional interface between HyperWorks and ESAComp is mature enough to be tasked with RUAG's demanding real cases: set up the finite element model, to run the quasi-static and dynamic load cases and to evaluate the results.”
–Ralf Usinger, Product Lead Engineer Satellite Structures

Data Bank and multi-level database - The ESAComp Data Bank includes data for a wide selection of composite materials and material systems. User and company specific material libraries can be stored in the database, as well as data related to design studies (laminates, structural elements, loads,…).

Design environment - ESAComp forms an efficient platform for performing design studies of composite structures. The graphical result displays help in performing trade-off studies between materials and structural alternatives.

Design optimization - Besides the user environment that allows practical hands-on optimization of designs, ESAComp integrates as part of more complex optimization systems involving optimization and FE software.

Detailed documentation - ESAComp with its documentation helps structural engineers with limited composites experience to get familiar with the topic. At the same time, ESAComp goes in-depth in a way that allows even composites experts to learn new.

Multiple analyses and graphic display of results - The user has almost limitless options for selecting and combining the resulting data and to display it as numeric tables, layer, bar, line, and polar charts, carpet plots, failure envelopes and 3D contour plots.

ESAComp analysis and optimization capabilities were used in the design of the Biofore Concept Car. ESAComp allows quick modeling of stiffened composite panels for preliminary dimensioning. From concept to final composite structure – the marine industry is among those that utilize ESAComp. Biofore Concept Car applies composites in innovative ways – with some help from ESAComp. ESAComp can optimize the lay-up and geometry of structural elements together with HyperStudy. ESAComp enhances the post-processing capabilities of HyperWorks for composite structures. ESAComp interfaces with HyperWorks for both pre- and post-processing. For the analysis of cylindrical structures, ESAComp can be used with a winding simulation tool.

Analysis capabilities - Micromechanics, laminate stiffness and hygrothermal expansion, laminate failure with selected failure criterion (incl. advanced criteria like Puck 2D/3D), sandwich failure modes, rectangular panels (flat and curved), stiffened panels, beams, bonded and mechanical joints, probabilistic analyses, moisture diffusion…

FE export - Material and laminate data is exported in solver dependent format for various HyperWorks supported profiles (OptiStruct, NASTRAN, Abaqus, ANSYS, LS-DYNA).

HyperWorks integration - ESAComp post-processing interface in HyperWorks allows transfer of FE results and related material and lay-up data to ESAComp for failure analysis and for further visualization of results in HyperView.

SI and British/U.S. units - Units and output formats can be changed at any time during the session.

User extensions - User modules can be integrated in the system and ESAComp analyses can be incorporated into other applications by running ESAComp in batch mode.
