Improving wood strength and stiffness through viscoelastic thermal compression

Creator:: O'Connor, John P.
Abstract:: The objective of this research project was to increase the density, strength, and stiffness of two low to medium-density diffuse-porous hardwood species. Wood used in this study was processed using a method of wood densification known as “Viscoelastic Thermal Compression” (VTC). The VTC process is a three phase treatment which...

Investigation of Thermal Degradation in Structural Alloys for Nuclear Power Systems

Creator:: Teng, Fei
Abstract:: The thermal degradation of structural materials is considered to be a key factor for evaluating the lifetime of current nuclear power plants. Ni-based and Fe-based alloys, such as 690, 625, 304, and 316, are widely used in nuclear industry as structural components due to the extraordinary corrosion resistance and mechanical...

The effect of elevated temperature on mechanical behavior of structural wood and wood-based composites

Creator:: Sinha, Arijit
Abstract:: Engineers, in practice, are often faced with the challenge of evaluating a fire-damaged structure and developing a rehabilitation and retrofit plan. In order to decide on a rehabilitation and retrofit plan, information on thermal degradation of building materials and connections are vital. A critical knowledge gap exists in terms of...

Improving the Performance of High Early Strength Concrete by Controlling Self-Desiccation and Mitigating Shrinkage

Creator:: Wilson, Cameron A.
Abstract:: High early strength (HES) concrete is becoming increasingly used to repair damaged concrete pavement sections. The use of HES concrete enables the repaired pavement to be opened to traffic within hours of placing the concrete. A common approach used for the rapid repair of concrete pavement consists of closing a...

Structural analysis of thermally inactivated nisin

Creator:: Musafija-Jeknic, Tamara
Abstract:: Nisin, an antimicrobial peptide used in food preservation was evaluated for thermal stability. Nisin retained antimicrobial activity after having been heated at 121°C for seven hours. Anhydrous nisin and concentrated nisin solutions (5-10 mg/ml) were still active after having been heated up to 190°C or 230°C. When exposed to high...

Large-strain softening of aluminum in shear at elevated temperature

Creator:: Alhajeri, Saleh N.
Abstract:: Pure aluminum deformed in torsion (shear) at elevated temperatures reaches a broad "peak" stress and then undergoes about a 17% decrease in flow stress with deformation to roughly 1-2 equivalent uniaxial strain. Beyond this strain the flow stress is approximately constant. The sources for this softening are unclear. The suggested...
