Structural components made of glass-fiber reinforced plastic (GFRP) fabricated into complex-profile linear shapes are widely used today in aerospace, civil infrastructure and other industries. Examples include aircraft structural components, elements of power line support structures, and bridge structural elements such as beams, decking and girders. Although somewhat more expensive than comparable components made of traditional materials such as metals, concrete or wood, polymer composite structures can have decisive advantages over their traditional counterparts, especially where weight or corrosion resistance is critical.
However, they still need to be cost-effective. One way to achieve this is by taking advantage of GFRP’s ability to be fabricated into large integral structures with lower production costs than counterparts made of traditional materials. While feasible and already applied in various industries today, this approach requires sound understanding and control of the fabrication process to avoid process-induced shape deformations. When the dimensions of finished items fall outside specified limits, misfits or clashes result when assembling components of complex structures.
The challenges of fabricating GFRP components within specified dimensional tolerances have conventionally been solved experimentally, through trial-and-error variation of process parameters during fabrication. This iterative procedure is expensive, labor-intensive and, above all, not very effective, especially when fabricating large components. Thus, industries that rely on GFRP components have an urgent need for mathematical models that effectively predict process-induced residual stresses and deformations, and reveal how to improve and optimize the fabrication process.

DATADVANCE is adding new features and functionality to its pSeven design space exploration software platform at a lightning pace. pSeven 6.6 Release was unveiled April 5, followed by pSeven 6.7 three days ago. Highlights of the two releases include a new interactive Predictive Modeling Toolkit built on the company’s pSeven Core algorithms (formerly called MACROS), new ANSYS Workbench integration, and a rich array of feature updates and enhancements to further increase pSeven’s performance, stability and ease of use.
Highlights of pSeven 6.6 that make predictive modeling and data analysis easily available: Continue reading
DATADVANCE presented pSeven Cloud, the first full-cloud design space exploration platform, at the NAFEMS European SPDM Conference held Dec. 2-3 in Munich. pSeven Cloud is part of the emerging new generation of full-cloud design and simulation software tools such as Onshape, SimScale and Sim4Design. DATADVANCE CEO Sergey Morozov showed how pSeven Cloud complements those design and simulation tools by adding the critical capability of design space exploration, essential for implementing simulation-driven design methodology. Based on DATADVANCE’s efficient, production-proven data analysis and optimization algorithms, pSeven Cloud features the company’s SmartSelection™ metaheuristics that automatically selects the most appropriate and efficient analysis or optimization method based on the user’s description of the problem.

Accurate calculation of the solvation parameters of organic molecules, important in many aspects of research in the pharmaceutical and agrochemical industries, is a longstanding challenge in computational chemistry. For example, many of the pharmacokinetic properties of potential drug molecules are defined by their solvation and acid-base behavior, which can be estimated from their hydration free energies. Solvation, also sometimes called dissolution, is the process of attraction and association of molecules of a solvent with molecules or ions of a solute; as ions dissolve in a solvent, they spread out and become surrounded by solvent molecules.

Waveguides are structures that guide electromagnetic waves, sound waves or other kinds of wave. Their function is to propagate a signal while minimizing energy loss by restricting its expansion to one dimension or two. A common application is signal transmission between components of a system such as a radio, radar, or other electronic or electro-optical device. This case involved bi-objective optimization of a waveguide for correct power split with minimal reflection loss. Continue reading
