Experience

Venkata Nadakuditi specializes in strength, fatigue and fracture mechanics in metals with primary interests in steel structures and pressurized containing systems. Prior to joining WJE in 2016, Mr. Nadakuditi spent his career in the oil and gas industry. His past work included extreme event strength assessments, extreme event strain-based assessments, defect acceptance criteria, fatigue life predictions, and experimental testing. He has experience using API 579, BS 7910, ABAQUS finite element software, special purpose fracture mechanics software programs, classical methods, and design documents (e.g., API, ASME, AISC, BS, DNV) to calculate defect acceptance criteria, material requirements, remaining fatigue lives, strength, and ductility.

Mr. Nadakuditi’s graduate studies focused on the seismic analysis of horizontally curved steel girder bridges and their parametric response. Since 2006, he has gained experience using ABAQUS.
