My primary research interests are in multiscale methods, design optimization for additive manufacturing, and nanomechanics. Currently, my research group is actively working on developing the "Lattice Structure Design Optimization" software for generating optimal lightweigt design for 3D printing.

I joined University of Pittsburgh in 2008 as assistant professor and have been associate professor since 2014.  I am also directing the ANSYS Additive Manufacturing Research Laboratory at Pitt, which houses several of the most advanced metal and plastic 3D printers including the EOS DMLS, Optomec LENS, ExOne binder jetting, and Stratasys Objet systems.

I did my undergraduate study at UC Berkeley and master's study at MIT. I obtained my Ph.D. from UC Berkeley under the supervision of Shaofan Li and Steve Glaser. I also conducted postdoctoral research with Wing Kam Liu at Northwestern University.

My research has been supported by NSF, America Makes, DoD, NRC, Pennsylvania Commonwealth, ANSYS, etc.  I am collaborating with the industry extensively in my computational research for additive manufacturing.

I received the NSF BRIGE award in 2009.

 

I am currently looking for new Ph.D. students interested in constitutive modeling or topology optimization for additive manufacturing.  Send me a copy of your resume if you are interested.

SOFTWARE

Want to learn topology optimization?  MATLAB codes for the Proportional Topology Optimization (PTO) method solving the minimum compliance and stress constrained problems are available to download for free (www.ptomethod.org).  See also the paper on the method:  E. Biyikli and A. C. To, "Proportional topology optimization:  A new non-sensitivity method for solving stress constrained and minimum compliance problems and its implementation in MATLAB,"PLOS ONE, 10, e0145041, 2015.  [link]

My two former students Emre Biyikli and Qingcheng Yang have been developing the Multiresolution Molecular Mechanics (MMM) method since 2012 and wrote their Ph.D. dissertations about it.  The MMM method is a concurrent coupled atomistic-continuum method similar to the energy-based Quasicontinuum (QC) method.  You can read more about it in the MMM section below.  The C++ source code for implementing the MMM method can be downloaded by following this [link].

Topology Optimization of AM Cellular Structures

 

Cellular structures can be employed effectively in lightweight structural design to overcome some of the manufacturing limitations existing in additive manufacturing (AM). For this purpose, a homogenization-based topology optimization method is proposed to optimize variable-density cellular structures efficiently. First, homogenization is performed to capture the effective mechanical properties of cellular structures through the scaling law as a function of relative density. Second, the scaling law is employed directly in the topology optimization algorithm to compute the optimal density distribution for the part being optimized. Third, a new technique is presented to reconstruct the CAD model of the optimal variable-density cellular structure. The proposed method is validated by comparing the results obtained through homogenized model, full scale simulation, and experimentally testing the optimized parts after being additive manufactured. The test examples demonstrate that the proposed homogenization-based method is efficient, accurate, and is able to produce manufacturable designs.

Modeling Microstructure and Property of AM Metals

 

Advances in additive manufacturing (AM) technology have made it possible to manufacture complex-shaped metal components strong enough for real engineering applications. To date, the process-microstructure-property relationship for AM metals has mostly been investigated experimentally, which is expensive and time-consuming since the parameter space is quite large. The lack of a reliable theoretical model for predicting such relationship makes it difficult to design AM components. The goal of this research is to establish a theoretical model that is capable of predicting the microstructure (texture, grain size, shape and subgrain features length scale) and mechanical properties (strength and anisotropy) of an AM metal based on the input process parameters (beam power, scan speed, preheat, and scanning strategy).

Multiresolution Molecular Mechanics

 

In the last five years, we have been developing a new energy-based concurrent atomistic/continuum framework called the Mutiresolution Molecular Mechanics (MMM) that includes formulation for both the statics (MMS) and dynamics (MMD) methods. By introducing a novel energy sampling framework, MMM aims at accurately and efficiently approximating the atomic energy of the system at different resolutions without the cumbersome interfacial treatment in existing methods. The key features of the MMM method are: (1) consistency with the atomistics framework, (2) consistency with the order of shape functions introduced, and (3) flexibility in energy approximation with respect to accuracy and efficiency. Under the energy sampling framework, several sampling schemes have been devised and tested for interface compatibility, and compared to existing methods. The proposed MMM method demonstrates very good accuracy in solving many different problems such as crack propagation and surface relaxation problems when compared to full molecular statics.

Mechanics of Bioinspired and Phononic Structures

We believe nature optimizes certain mechanical properties of biological materials by designing microstructure. Recently, we have discovered interesting mechanical behaviors in hierarchical structure found in many biocomposites. For example, hierarchical structure can enhance wave filtering and damping figure of merits significantly.
