Poking/pressurizing thin elastic sheets with sliding boundaries

Dear iMechanicians, I would like to share our recent work on the poking and bulging of elastic thin sheets that were inspired by the classical indentation test and bulge test. Under clamped boundaries, there have been well-established theories and well-controlled experiments in this field.

The poker-chip experiments of Gent and Lindley (1959) explained

Despite being commonly credited with initiating the field of cavitation in elastomers, the famed poker-chip experiments of Gent and Lindley (1959) have yet to be fully explained. One likely reason for their elusiveness is that it had long been presumed that cavitation in elastomers was a phenomenon that could be explained solely on the basis of the elasticity of the elastomer at hand.

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 https://www.youtube.com/watch?v=7d5LuQrLpCM&t=5s.

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

Background

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

Objective

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.
