Abstract: In this paper, we demonstrate a novel Nano-indentation Dynamic Mechanical Thermal Analysis (NiDMTA) technique to measure storage and loss moduli of a polymeric material over combined ...

Thermoplastics are used to make a variety of everyday items. These polymers are distinguished by their ability to soften when heated and harden when cooled. In their molten state, they can be ...

Dynamic bonds have been found to enhance fracture toughness of hydrogels as sacrificial bonds, but the role of dynamic bonds to fatigue threshold of hydrogels is poorly understood because the wide ...

Asphalt mixtures are commonly used in pavement engineering, especially for highway construction. The mechanism exploration and analysis of pavement distress are the main challenges for researchers and ...

Using various tools to obtain downhole data to reach a precise pore pressure model is an important means to predict overpressure. Most downhole tools are connected to the lower end of drill string and ...

Dynamic Modulus, E is a complex parameter that relates stress to strain of a linear viscoelastic material as a function of loading rate and temperature. It Describes how the stiffness of HMA mixtures ...

Atomic force microscopy (AFM) offers nanoscale mapping of materials’ properties. Especially, our modified AFM termed “nanorheological AFM” enables us to measure the accurate frequency-dependent ...

The mechanical behavior of viscoelastic materials is influenced, among other factors, by parameters like time and temperature. The present paper proposes a methodology for a thermorheologically and ...

Building on recent statistical mechanical theories of segmental activated barrier hopping and elasticity in quiescent and stressed polymeric materials, we construct a constitutive equation description ...
