Work Experience :
Stress Engineer, Goodrich Cargo Systems, Jamestown, ND. (01/07 to 02/22/2010)
Job duties as a stress engineer : Goodrich cargo systems include,
- Generating applied loads and interface loads.
- Understanding design constraints and coordinate design requirements, structural design modifications with the design, manufacturing and other personals as required.
- Conducting preliminary stress check for cargo flight (Boeing 777F Main Deck & 787 Lower Deck) hardware parts and assemblies, using both classical analysis and finite element analysis.
- Preparing the test request for static tests, providing detail analysis test predictions and conducting, documenting and correlating the test results to the existing analysis to meet the requirements.
- Reviewing and approving the structural drawings.
- Reviewing and updating the stress analysis reports to meet the production requirements.
- Generating formal FAA stress reports validating components meet requirements and specifications.

777F Maindeck Projects :
Side Guide Support Transition Loads Analysis :
- Worked as one of the member of a two member team for this assignment and the objective was to capture the applied loads to the side guide supports where both attenuated and non-attenuated side guide supports are present.
- A Finite element model was developed to capture the loading scenario for critical loading conditions. Solid elements and spring elements were used in this model. The stiffness of the aircraft structure was also used in the model per customer direction.
- The results obtained from finite element analysis were validated classical hand analysis and Beam 2-D software.
- Aircraft structure stiffness and side guide support stiffness was used in Beam 2-D model. Side guide support stiffness was calculated from load vs deflection curve obtained from a static test conducted in the lab.
- There was less than 10% difference in loads obtained from Beam 2-D and finite element analysis.

Side Guide Assemblies :
- Developed a Finite element model to capture the critical loading conditions using beam elements. Critical forces and moments were obtained from finite element model.
- Customer provided tools were used to substantiate the design using the forces and moments obtained from finite element model.
- Developed customer deliverable stress reports meeting the requirements.
- Reviewed and approved structural drawings.

Roller Tray Assemblies :
- Developed Interface loads from roller trays to aircraft structure.
- Beam 2-D software was used to model critical loading conditions. Maximum forces and moments for critical loading scenario were obtained from Beam 2-D analysis.
- Formal stress report with structural substantiation was developed for customer approval.
- Structural drawings were reviewed and approved for production and customer vendor drawing approval.

Freighter Common Turntable :
- Had a limited role in this assignment. The objective was to chase the applied loads through the detail parts in the assembly, creating free body diagrams and establishing load paths for the substantiation of the detailed parts in the assembly.
- Contributed towards the fatigue analysis of few detailed parts.

787 Dreamliner Lower Deck Projects :
Allowable Damage Limit, Lock Trays
Developed stress report with stress substantiation for allowable damage limits on Lock trays/Roller trays for DER approval.

Rejection Tags :
- Worked on few rejection tags providing stress substantiation for manufacturing problems.
- Coordinated the results to the stress lead, production and document the results as strength check notes to aid thee drawing approval.

Pallet Lock Test support :
- Developed test report with list of objectives and test procedure for pallet locks static test.
- Created strength check notes providing the predictions for the test.
- Strength check notes involved running finite element models and classical hand analysis to support the predictions.

Interface Loads Document :
- Worked for completing the interface loads document per stress lead engineer comments for DER approval.

747 Maindeck Ball Mat Panel Repair :
- Suggested the repair and provided the stress substantiation for the Ball mat panel top skin repair.
- Reviewed and approved structural drawings for the repair.

A320 Freighter Cargo Handling System Proposal :
- Worked within a five member team to come up with a cost and time effective system for the proposal.
- My role was to develop the applied loads for the system per customer requirements and help the design group with preliminary designs.
Was involved with number of other projects to create the stress reports for customer approval, interacted with customer to expedite the approval process and updated the stress reports per customer requirement to make the reports FAA approvable. Reviewed the stress analysis reports of other analyst as a part of peer review before the stress reports were send to customer for their approval.
Graduate teaching assistant for Engineering Design course and Statics course (Fall 2006), Material Properties and Selection course in Spring 2006, Industrial noise control course in Spring 2006, Kinematics and Dynamics of machines course in Fall 2005, Dynamics course in Fall 2005. Duties include taking classes in the absence of the Professor, grading the assignments, conducting help sessions, preparing timely reports on the progress of the class.

Master Thesis :
Thesis on “The Effect of processing parameters on the deformation/fracture of Aluminum 2024”
- An experimental study on the influence of parameters on the structural strength of Aluminum alloy.
- The parameters considered are temperature, time at the temperature, cooling rate and aging time.
- Box-Behnken design is currently being used for the statistical analysis of the data (JMP Software).
- Image-J software is used to study the microstructure of the specimen.
- Final goal of this project is to correlate the process parameters and the deformation of the material.
- Planned, conducted, and performed the experimentation and the data analysis.
- Includes report writing and presentation with the thesis committee.
- Statistical relationships from this research will aid in the development of a predictive numerical model that will be implemented in a FEA program.

Undergraduate Project :
Project : “Effect of process parameters on final flow formed tube” at Bharat Dynamics Limited, Hyderabad a Ministry of Defense, Government of India institution, 2004.
- Flow forming is a continuous, progressive, localized deformation of the material, used to produce thin walled high precession tubes.
- The material taken for the study is Maraging steel (MDN-250), widely used in the missile and aerospace industry.
- In this project, the effect of the process parameters like roller radius, stagger, hardness of preform and feeds on the final flow formed tube dimensions were investigated.
