Structure Genome: a Unified Multiscale Approach to Bridging Materials Genome and Structural Analysis

After almost seven years development, we have achieved more and more clarity with the concept of structure gene and it governing principles (mechanics of structure genome). My recent talk on MSG summarizes its relations with materials genome, common structural theories, micromechanics, multiscale modeling, as well as its current application to deployable structures, homogeneous 3D elements, machine learning assisted multiscale modeling. You can watch this talk at Youtube

Analytical Model and Experimental Verification of the Interfacial Peeling Strength of Electrodes


The interfacial peeling strength of lithium-ion battery electrodes is a very important mechanical property that significantly affects the electrochemical performance of battery cells.


To characterize the interfacial peeling strength of an electrode, an analytical model based on the energy balance principle is established by considering the state of charge (SOC), the energy release rate, the tensile stiffness, and the peeling angle.

Achieving selective snapping-back and enhanced hysteresis in soft mechanical metamaterials via fibre reinforcement

When a soft mechanical metamaterial, consisting of a regular array of representative volume elements (RVE), is stressed up to a large strain, the delicately tailored behavior of the RVE does not prevail in the metamaterial due to boundary effect and manufacturing imperfections.

Development and Characterization of Ti/SiC Metal Matrix Nanocomposite Coating with Superior Surface Properties

In this work, a Ti/SiC metal matrix nanocomposite (MMNC) coating was produced on Ti-6Al-4V substrate by Selective Laser Melting (SLM) technique. The MMNC coating had 7% SiC and 93% Ti by volume. It was observed that applying the nanocomposite coating on titanium substrate significantly reduced the wear and coefficient of friction (COF). By applying the coating, 108% improvement in hardness of Ti-6Al-4V substrates was obtained. The MMNC coating also showed a COF of 0.38 as compared to 0.42 for the Ti-6Al-4V substrate.

On the origin of supercontraction in spider silk

Spider silk is a protein material that exhibits extraordinary and nontrivial properties such as the ability to soften and decrease its length by up to ∼60% upon exposure to high humidity. This counter-intuitive process is commonly called supercontraction and is the result of a transition from a highly oriented glassy phase to a disoriented rubbery phase. In our new paper (published in biomacromolecules) we derive a model that explains the origins of the supercontraction phenomena.

MULTIPLE GRADUATE STUDENT openings in Mechanical & Aerospace Engineering at University of Texas at Arlington, Texas, USA.

Our group has several openings for fully-funded graduate students in computational and experimental mechanics of biological and engineered materials. Our primary goal is to link traumatic brain injury (TBI) with multiscale, multiphysics damage evolution in the brain using experimentally verifiable computations and simulations. We are also interested in designing advanced material for TBI protection.

Experimental observations of nonlinear vibration localization in a cyclic chain of weakly coupled nonlinear oscillators

Experimental results on nonlinear vibration localization in a cyclic chain of weakly coupled oscillators with clearance nonlinearity are reported. Numerical modelling and analysis complements the experimental study. A reduced order model is derived and numerical analysis based on the harmonic balance method demonstrates the existence of multiple classes of stable spatially localized nonlinear vibration states. The experiments agree very well with the numerical results.

Dynamic Modelling of a Hydraulic Engine Mount Including the Effects of Elastomer Aging

In this article, the effect of material aging of an elastomeric main spring (MS) inside a hydraulic engine mount (HEM) on its dynamic performance is investigated. A set of HEMs aged under realistic operational conditions are used to create an empirical material aging model of the elastomer at two different temperatures (35°C and 95°C) using dynamic mechanical thermal analysis (DMTA).

A unified mechanics theory-based model for temperature and strain rate dependent proportionality limit stress of mild steel

Strain rate and temperature dependent elastic limit of mild steel is investigated by developing a dislocation incipient motion-based proportionality limit stress model. Temperature effect on strain energy of an edge dislocation is modeled by using unified mechanics theory. Unified mechanics theory-based index, called thermodynamic state index, is used to model thermally assisted degradation of strain energy. Kinetic energy due to thermal vibrations is added to the kinetic energy of an accelerating dislocation.

Vibration localization due to flutter instability in a bladed rotor

The current push toward lightweight structures in aerospace and aeronautical engineering is leading to slender design airfoils, which are more likely to undergo large deformation, hence experiencing geometrical nonlinearities. The problem of vibration localization in a rotor constituted by N coupled airfoils with plunge and pitch degrees of freedom subjected to flutter instability is considered.

Does roughness enhance or destroy adhesion????

Recently, Dalvi and co-authors have shown detailed experimental data of adhesion of soft spheres with rough substrates with roughness measured down to almost the atomic scale, finding that the Persson and Tosatti theory gave satisfactory predictions of the apparent work of adhesion during loading, once the increase of the surface area due to roughness is correctly computed at extremely small scales.

EML New Year Message

Dear Friends of EML,

Happy New Year! 

2020 was an extremely challenging year for all because of COVID 19. For most of us, the lockdowns and work from home negatively impacted our research activities; for some, it provided a time to reflect on the value of our work; and, for a few, it presented an unusual opportunity to explore new directions of research.
