Design to Life Assessment

Valve Failure Assessment

We have a team of experts with decades of experience in solving complex fatigue life assessment, fracture / crack growth simulations, failure assessment – with experience in correlating theoretical, analytical, practical and computational results.

Fatigue, Durability Evaluation

This team supports you  evaluation of Fatigue, Durability or life assessment.  Mainly deals with – Structural Fatigue, Thermal Fatigue, Vibration Fatigue, Weld Fatigue, Thermo-Mechanical Fatigue, Creep Fatigue Interaction, Fatigue Property Derivations, Physical correlations and simulation. Prediction da/dN, crack Initiation, FOS, No. of Cycle to Failure, LCF, HCF, design life estimation

 Fracture Mechanics & Failure Analysis

This team supports you  Fracture Mechanics Simulation – Crack Growth Simulation, da/dN, crack Initiation, Crack Growth, toughness, Impact, Failure, Dynamic, SIF, M & J Integral. Failure analysis team does an detailed mechanical, material and metallurgical studies in predicting the source of failure, failure mechanisms, mode of failure. basically involves failure investigation and forensic services.

Multi – Scale Material Modeling

This team supports you evaluation of the materials at a nano, meso, micro and macro scale modeling of material through molecular dynamics, quantum mechanics, finite element modeling. Material Characterisation, Material Property Derivations, Calibrations, Virtual Evaluations. Studies includes development of new materials (plastics, ceramics, composites, alloys of metals, etc) to meet different functional needs. Derivation of constitutive equations from the material testing procedures is an involved science
