Education
Brief Bio
Dr. Madireddy is a Research Scientist in Arbegast Materials Processing and Joining (AMP) Laboratory. At the AMP lab Dr. Madireddy is leading computational research efforts in various manufacturing technologies such as additive manufacturing, ballistic impact, cold spray, and friction stir processing technologies. Prior to his appointment at SD Mines, Dr. Madireddy worked as additive manufacturing scientist at Sentient Science and as postdoctoral researcher at Oak Ridge National Laboratory.
Research Expertise
Dr. Madireddy’s research expertise lies at the intersection of manufacturing technologies,
hybrid processing, and computational modeling. His work focuses on understanding and
controlling residual stress formation, distortion, and microstructural evolution in
various manufacturing processes such as directed energy deposition, powder bed fusion,
and wire arc additive manufacturing, friction stir processing, cold spray, and ballistic
impact testing. He has pioneered research in hybrid additive manufacturing (hybrid-AM)
that integrates additive with secondary processes such as surface treatment processes
(e.g., laser shock peening and ultrasonic impact treatment) or subtractive processes
to enhance part/process performance.
Dr. Madireddy has extensive experience developing finite element models to simulate
thermo-mechanical behavior, phase transformations, and process-structure-property
relationships. Overall, his research aims to advance next-generation manufacturing
technologies by integrating computational modeling with in-situ monitoring, microstructural
and mechanical characterization (SEM/EBSD, XRD, hole drilling, microhardness, fatigue
and tensile testing), and machine learning based process mapping to optimize process
parameters and mitigate defects across various manufacturing processes.
