RISUndrained Response of Clays to Varying Strain Rate
Publisher: American Society of Civil Engineers
Abstract: The undrained stress–deformation behavior of clays is significantly affected by the loading rate. Based on the observed experimental response, it is possible to model the strain rate response of clays as an apparent ...
Modeling and Testing of Cohesive Soil Using Disturbed-State Concept
Publisher: American Society of Civil Engineers
Abstract: A new constitutive model for predicting the undrained stress-deformation and pore water pressure response of saturated cohesive soils subjected to cyclic loading is developed using the disturbed-state concept (DSC). The ...
Nanoscale Morphology of Kerogen and In Situ Nanomechanical Properties of Green River Oil Shale
Publisher: American Society of Civil Engineers
Abstract: Oil shale is an important energy resource that is immensely underutilized due to the cost of extraction of crude oil from oil shale as a result of limited scientific understanding of the locking of kerogen, the precursor ...
Insight into Role of Clay-Fluid Molecular Interactions on Permeability and Consolidation Behavior of Na-Montmorillonite Swelling Clay
Publisher: American Society of Civil Engineers
Abstract: Swelling clays, also known as expansive clays, are encountered extensively all over the world. These clays are problematic for geotechnical engineering applications because of distress caused to structures and infrastructure ...
Nanoclay Based Composite Scaffolds for Bone Tissue Engineering Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Scaffolds based on chitosan/polygalacturonic acid (ChiPgA) complex containing montmorillonite (MMT) clay modified with 5-aminovaleric acid were prepared using freeze-drying technique. The MMT clay ...
Experiments in Nanomechanical Properties of Live Osteoblast Cells and Cell–Biomaterial Interface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Characterizing the mechanical characteristics of living cells and cell–biomaterial composite is an important area of research in bone tissue engineering. In this work, an in situ displacement-controlled ...
Steered Molecular Dynamics Study of Mechanical Response of Full Length and Short Collagen Molecules
Publisher: American Society of Civil Engineers
Abstract: Collagen is a fibrous protein that is responsible for structural integrity of various connective tissues such as bone, tendon, and skin. The mechanical properties of these hierarchical tissue structures are greatly influenced ...

Publisher:
Abstract: Oil shale is an important energy resource that is immensely underutilized due to the cost of extraction of crude oil from oil shale as a result of limited scientific understanding of the locking of kerogen, the precursor ...
Mechanisms of Load-Deformation Behavior of Molecular Collagen in Hydroxyapatite-Tropocollagen Molecular System: Steered Molecular Dynamics Study
Publisher: American Society of Civil Engineers
Abstract: Bone is a widely studied structure due to its important function in the human body and also for its unique mechanical properties, which depend upon several factors, such as, its hierarchal structure, its constituents, ...
Nanomechanics of Surface Modified Nanohydroxyapatite Particulates Used in Biomaterials
Publisher: American Society of Civil Engineers
Abstract: Hydroxyapatite is an important constituent of natural bone, and possesses excellent biocompatibility and bioactivity, but its brittle nature limits its use for bone tissue engineering. Nanohydroxyapatite (nanoHAP) has been ...
