Structural Analysis

AltaSim Technologies' staff has more than 25 years expertise in the development and application of finite-element based analysis using ABAQUS. We have applied ABAQUS to understand the behavior of laboratory-based tests and the response of large scale complex structural components. AltaSim's engineers can accurately simulate the behavior of a range of conditions including:

• Linear and Non-linear materials and structural behavior
• Combined structural and thermal loading (thermomechanical analysis)
• Fracture mechanics (linear and nonlinear)
• Component lifetime assessment, structural stability, and identification of safe operating conditions and inspection intervals
• High-rate loading including impact, metal forming and explosive loading of water (UNDEX) and land based (AIREX) applications
• Heat transfer due to conduction, convection and radiation
• Large deformation using explicit solver techniques
• Surface contact, impact analysis and inelastic buckling phenomena
• Structural vibration
• Complex materials response including linear, non-linear and time dependent behavior including traditional structural, thermo-elastic/plastic and biomaterials
• Specialized user material models (UMATS)

Over the years, AltaSim's expertise in these areas has supported a wide range of technology developments including the design of large scale ship structures subject to high rate loading and small scale implanted medical devices under loading from human body activity; the identification of safe operating limits and inspection intervals for damaged petrochemical plants, and the manufacturing conditions for automotive component production; the impact of manufacturing induced residual stresses on the behavior of complex structures and the development of material processing and manufacturing operations.
