Position: Post-Doctoral Researcher
Institute: Purdue University
Duration: June 2021-November 2022
Project: Spring-in and Wrinkle Prediction in Stamp Formed Thermoplastic Composite Parts
Performed a sequential thermo-mechanical analysis (using AniForm, 3DEXPERIENCE Platform, ABAQUS) on a thermoplastic composite stamp formed part to predict its shape change during and after the final machining operation. The findings are validated by conducting experimental studies.
Performed a forming analysis (using AniForm) to predict out-of-plane and in-plane wrinkle formation on a thermoplastic composite stamp formed part. The findings are compared against the experimental observation.
Project: Infer and Transfer Thermo-Mechanical Properties of Short-Fiber-Reinforced Polymer Composites Across Different Additive Manufacturing Printing Systems
Developed a Mori-Tanaka micro-mechanics model-based inference framework (implemented using a Python script and Digimat) to infer the coefficients of thermal expansion (CTEs) of the constituent fiber and matrix for a printing system of interest.
Used the inferred values to predict the CTEs of the same material printed in another printing system, thus reducing the experimental efforts of characterization significantly. The predicted values are validated by performing some experiments.
Performed sequentially coupled thermo-mechanical additive manufacturing simulation for different geometries (using ABAQUS) and demonstrated that the spring-in deformation in these parts using the predicted composite CTE values matched closely with the experimental observation.
Used a similar methodology (Bayesian inference framework) to infer and transfer thermal conductivity properties of the constituent fiber and matrix.
Project: Flexure Behavior of a Honeycomb Sandwich Panel
Performed 4-point bending simulation (using ABAQUS) on a Nomex honeycomb sandwich panel, which is used to make Big Tracker Support Tube structure in CERN. The findings are validated by conducting experimental studies.
