Influence of transverse-shear and large-deformation effects on the low-speed impact response of laminated composite plates [PDF]

An analytical procedure is presented for determining the transient response of simply supported, rectangular laminated composite plates subjected to impact loads from airgun-propelled or dropped-weight impactors. A first-order shear-deformation theory is

The exponentiated Hencky strain energy in modelling tire derived material for moderately large deformations

, 2015
This work presents a hyper-viscoelastic model based on the Hencky-logarithmic strain tensor to model the response of a Tire Derived Material (TDM) undergoing moderately large deformations.

Multiscale Hybrid Surface Topographies Orchestrate Immune Regulation, Antibacterial Defense, and Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Hybrid wrinkled topographies coordinate immune, tissue, and bacterial interactions. The surfaces promote osteointegration, tune macrophage polarization, and inhibit biofilm formation, highlighting a multifunctional strategy for next‐generation implant design.

Irreversible thermodynamics of creep in crystalline solids

, 2013
We develop an irreversible thermodynamics framework for the description of creep deformation in crystalline solids by mechanisms that involve vacancy diffusion and lattice site generation and annihilation. The material undergoing the creep deformation is

Compression‐Tension‐Asymmetry and Stiffness Nonlinearity of Collagen‐Matrigel Composite Hydrogels

Advanced Healthcare Materials, EarlyView.
Self‐assembled collagen hydrogel matrices are widely used in tissue engineering applications. These matrices stiffen and contract laterally under tension due to fiber alignment and soften and collapse under compression due to fiber buckling. It is demonstrated that filler materials, such as Matrigel, linearize the mechanical behavior of collagen ...

Buckling of Functionally Graded Nanobeams Based on the Nonlocal New First-Order Shear Deformation Beam Theory

MATEC Web of Conferences, 2014
In this work, the size-dependent buckling behavior of functionally graded (FG) nanobeams is investigated on the basis of the nonlocal continuum model.

A 3D Bioprinted Spheroid‐Laden dECM‐Enriched Osteosarcoma Model for Enhanced Drug Testing and Therapeutic Discovery

Advanced Healthcare Materials, EarlyView.
A 3D biomimetic OS model was developed by bioprinting an OS‐cell‐derived dECM‐enriched bioink with OS spheroids incorporated. The model showed upregulation of known OS prognostic markers and increased resistance to doxorubicin, compared to 2D cultures and scaffold‐free spheroids, making this a more clinically relevant platform for drug discovery ...

A Quantitative Printability Framework for Programmable Assembly of Pre‐Vascular Patterns via Laser‐Induced Forward Transfer

Advanced Healthcare Materials, EarlyView.
Laser‐Induced Forward Transfer (LIFT) is presented as a powerful micropatterning tool. An objective printability framework is developed to assess optimal printing parameter combinations. The technology is further explored for its ability to deterministically deposit microdroplets at predefined locations following CAD designs, enabling the patterning of

Dynamics of Viscoplastic Deformation in Amorphous Solids

, 1997
We propose a dynamical theory of low-temperature shear deformation in amorphous solids. Our analysis is based on molecular-dynamics simulations of a two-dimensional, two-component noncrystalline system. These numerical simulations reveal behavior typical
