Structural Analysis

The Kalsi Engineering staff has a strong background in the classical strength of materials. This knowledge has been reinforced through practical applications of the ASME Boiler and Pressure Vessel Code (BPVC) and API Specification 6A, 7, 7G and 579-1. Our core background in solid mechanics, elasticity, plasticity, fracture mechanics, and theory of plates and shells coupled with our extensive knowledge of finite element methods and on-site mechanical laboratory makes us well positioned to address your structural analysis needs.

KEI™ serves the US and International Nuclear Power Industry and provides structural analyses under a Quality Assurance program that complies with the requirements of ASME NQA-1.


Kalsi Engineering provides the following structural analyses services:

  • Component limit evaluation
  • Fatigue life evaluation
  • ASME BPVC Section VIII evaluation
  • ASME BPVC Section III evaluation
  • ASME B16.5 evaluation
  • API 6A, 7, 7G and 579-1evaluation
