Capabilities to Support R&D Projects
​
Durability:
o Many years of experience starting from complex FEA modeling to linear and nonlinear static and dynamic analyses supporting automotive, aerospace, and defense structures (including 3D printed and composites)
​
NVH (Vibration and Harshness)
o Frequency response analysis to calculate vibration-amplification factor and harshness analysis to calculate the time to damp down any external disturbances
o Tuning of rubber-mounts to keep vibration and shake within limits.
Load calculation using MBD and FEA analyses
o This is key in all aspects of durability analysis. Load calculation using either wheel-force-transducer test loads or road profile to predict durability
​
Highly Nonlinear Analysis such as Crash and Blast
o Many years of experience to analyze and improve the design for crash, door-slam, blast, etc.
​
Linear and Nonlinear Optimization
(including 3D printed and composites)
-
Linear Optimization
o Topology optimization to create design layout followed by fine tuning of shape and thickness to achieve targets. Many years of experience to create optimized components which went to production
​
o Optimization for high thermal loads --- is somewhat opposite to structural loads. Here, stiffer design is often a wrong design because high-temperature could lead to high-stress due to restricted thermal expansion. Have experience in an optimization strategy which is good for both structural and thermal loads

Nonlinear Optimization (Acceleration, Intrusion, and Directional-Fracture)
o Parametric nonlinear optimization are often done using external optimizers such as ls-OPT, HyperStudy, etc. But nonlinear topology optimization is a complex one. Ls-TaSC from LSTC/Ansys is a tool for solid-topology and varying thickness shell optimization. Recently, most of 3D-printed crash structures of a HyperCar was designed using this tool.
o Both parametric and topology optimization can be used to reduce acceleration and intrusion. In some cases such as crash-landing of aircraft and blast, they can be used to have a directional-fracture
