Hi everyone, I am a postdoc at Yale University. I am posting on some of my previous work on fiber networks and heterogeneous materials. We reported that effective stiffness is a concave function of inhomogeneity properties, and effective stiffness becomes smaller with increasing heterogeneity as an example consequence. 

Our new paper on ultrasonic vibration fatigue [a collaboration between 4 universities & 3 countries] is available for free access until  December 21, 2021,

In this journal club, we provide a brief summary on the concept, recent progress and tools of machine learning (ML) potential for atomistic materials modelling. We hope that it could benefit to the readers who are new to this filed and plan to develop their own or use others ML potentials. Comments and disscussions are welcomed. 

In this episode of Soft Robotics Podcast, the host Marwa Eldiwiny and I discussed our recent Science paper on fatigue-resistant hydrogel and elastomer. We talked about tanglemer, a polymer in which entanglements greatly outnumber crosslinks. We also talked about the background that motivated us, including fabrics, polymer metraix composites, ceramic matrix composites, metals.

Postdoc positions are available in Professor Min Luo’s group (https://person.zju.edu.cn/en/minluo) at the Ocean College of Zhejiang University, China. Those holding a Ph.D. degree in the area of Ocean/Coastal Engineering and Fluid Mechanics are welcome to apply. We are particularly interested in candidates with experience in Computational/Experimental Fluid Dynamics and data-driven simulation, etc.

The Journal of Engineering Mechanics (JEM) launches a series of high-profile special issues. The second in the series is dedicated to “Statistical Physics in Structural Mechanics”, guest edited by Mohammad Javad Abdolhosseini Qomi, University of California at Irvine and Andrej Kosmrlj, Princeton University. Submissions will be accepted until June 30, 2022.

For details, see the attached PDF file.

Two funded Ph.D. positions in the broad area of computational mechanics are available in Dr. Yuan’s research group (https://wp.wpi.edu/yuan/) at the Aerospace Engineering Department at Worcester Polytechnic Institute. Self-motivated individuals with research experience/ strong passion in ONE or more of the following areas are strongly encouraged to apply,

Our recent paper on predicting hydrogen damage in FCC steel single crystals. Most important thing about this paper is that the special issue is dedicated to Professor Siegfried Schmauder on his 65th birthday. Happy birthday Professor Schmauder and thanks for all your guidance, support and collaborations throughout my journey which still continues.
