Design Services
In partnership with our sister company, Cornerstone Research Group Inc. (CRG), we are able to offer complete design services to our customers. These services include CAD modeling and finite element analysis (FEA) stress analysis on parts varying in size from small remotely operated vehicle (ROV) components to buoyancy modules for the oil industry. Large system designs include analysis of attachment points, connections systems, and/or strapping to validate the performance of the entire system.

CRG uses ALGOR® and Abaqus® finite element modeling software to model and analyze composites, structures, and mechanical assemblies and to optimize their design. This finite element modeling package enables CRG to perform a broad array of analyses including linear and nonlinear stress, multiple-body contact, and interactions (mass, center of gravity, and mass moment of inertia) vibration, linear, and nonlinear heat transfer (steady-state or transient), and fluid flow (steady and unsteady).

ALGOR analysis

ALGOR and ABAQUS also provide CRG the capability to couple multiple analysis types. When heat transfer is coupled with stress analysis, they determine the effects of temperature on mechanical models composed of isotropic or orthotropic materials. When coupled with electrostatic analysis, the effects of Joule heating are determined. When coupled with fluid flow analysis, the effects of natural and forced convection are shown. When fluid flow is coupled with stress analysis, they determine the effect of stresses generated by fluid flows on applications such as containment vessels and interior constrictions.

This software is also capable of determining the buoyancy loss associated with a specific Advantic component or system as a result of water ingress, creep, elastic deformation, and temperature variation. CRG uses CATIA® drafting software to aid in modeling and design of parts and assemblies.
