ALTISS Technologies provides finite element analysis (FEA) services required for R&D, Fitness-For-Service, Forensic, Service Life Prediction and Third-Party Verification analyses.

ALTISS' FEA experts employ general purpose nonlinear finite element package ABAQUS®.  

ALTISS Technologies provides complete solutions for routine procedures as well as advanced analyses that allow engineers and designers to understand in-service performance of their products.

Finite element services offered range from turnkey modeling, analysis and reporting to a development of customary scripts for calculations required by ASME codes such as strain limit damage evaluation; and user subroutines simulating response of non-traditional materials.

ALTISS engineers focus on the following finite element topics:

• non-linear analyses of structures or components including the impact of thermal loads, cycling & vibration
• modeling traditional materials
• modeling of nonlinear materials such as plastic, hyperelastic and nonlinear viscoelastic 
• specialized techniques such as submodeling
• explicit quasi-static and dynamic methods
• development of user defined subroutines
• contact modeling
• fatigue and fracture analysis using traditional and XFEM methods
• convergence improvement

ALTISS utilizes state-of-the-art multiprocessor workstations which are able to solve in-core problems involving millions of unknowns.

ALTISS conducts client-specific training on advanced FEA subjects.
