Tissue engineering with soft matter
Published: February 22, 2022

http://s.uconn.edu/meseminar3/11/22 Abstract: The extracellular matrix (ECM) guides cells through mechanical and soluble signals among others. We guide cell behaviors using these two aspects of ECM.  Even the bone ECM is soft after de-mineralization. Thus, we are interested in soft polymeric materials. Many tissues in our body are elastic including blood vessels, our target tissue. We […]

On the stability and structure of turbulent premixed bluff-body stabilized flames at elevated pressure
Published: February 21, 2022

http://s.uconn.edu/meseminar2/25/22 Abstract: Energy conversion and propulsion systems operating with a lean, premixed mode of combustion are advantageous in terms of both emissions and economics. This is because fully premixing fuel and oxidizer prior to combustion can reduce harmful exhaust levels, while operating fuel lean ensures complete fuel consumption, providing superior fuel economy. In fact, it […]

The mechanical behaviors of bone across multiple length scales
Published: January 18, 2022

http://s.uconn.edu/meseminar1/28/22 Abstract: Bone is strong, tough yet lightweight, which can be attributed to its complex hierarchical structures across multiple length scales. The factors contributing to these superior properties are still not completely understood, especially its structure at the sub-micron- and nano-scales. The morphology and mechanical properties of bone are also affected by diseases and treatment. This […]

Manufacturability-driven, multi-component topology optimization (MTO) for top-down design of structural assemblies
Published: November 5, 2021

http://s.uconn.edu/meseminar11/12 Abstract: This talk presents a manufacturability-driven, multi-component topology optimization (MTO) framework for simultaneous design and partitioning of structures assembled of multiple components. Constraints on component geometry imposed by chosen manufacturing processes are incorporated in the conventional density-based topology optimization, with additional design variables specifying fractional component membership that enables continuous relaxation of otherwise discrete […]
