SIMULATION

Based on more than 20 years of experience, our staff has impressive expertise in the use of finite element analysis technology. With “virtual prototypes”, important benefits are obtained such as strength/weight ratio optimization, detection of potential problems, product performance enhancement, manufacturing cost reduction and finally, conformity to increasingly strict new product development standards. The following numerical simulations and optimizations are carried out on a regular basis by our team of experts:

Structural analysis
Analysis of the stress and strain of metallic structures, composites, plastics and elastomers is performed in order to optimize the weight, meet security requirements as well as applicable standards and specifications, to determine the optimal materials and processes and to assess the complete structural behaviour of the product. Compliance with current design rules and standards (ASME, DNV, R-CCM, etc.) is verified by means of accurate numerical simulation and analysis.   

Structural integrity assessment
Analysis of critical conditions or potential failure is fundamental in the assessment of safety operation of components.  Compliance with fracture mechanics requirements and damage tolerance acceptance criteria (R6, ASME, DNV, BS, etc.) is verified by means of extensive and detailed FEM analysis using advanced computational techniques such as: VCCT, domain integral, automatic crack growth analysis, etc.

Impact dynamics and shock compression
Analysis of materials and structures subjected to impulsive loading requires a deep knowledge of dynamic transient mechanics, stress wave propagation and material behaviour at high strain rates. Our staff has a long experience in the simulation of impacts, blast and explosion, fragmentation and target penetration using finite element codes (impicit and explicit) as well as hydrocodes.

High temperature design
Operating life in service at high temperature is controlled by a number of complex phenomena such as creep, creep-fatigue interaction, oxidation, damage and material instability. Our staff is highly qualified in the design of components operating at elevated temperature with particular reference to creep problems. Our capabilities include stress analysis with advanced proprietary constitutive models for: creep, creep-fatigue, creep crack growth (CCG) analysis.

Thermomechanical process simulation
Advanced simulation of production processes which includes material modification as a esult of the thermal and stress histories is fundamental for product optimization and innovation. Our company has implemented computational solutions for the simulation of materials subjected to thermo-mechanical processing (rolling, forging, stamping, etc..). With this tool is it possible to simulate and predict the microstructure evolution accounting for a number of processes such as grain growth, dynamic, static and metadynamic recrystallization, phase transformation, and more.
