Titanium alloys used for the manufacture of rotating parts of aircraft engines undergo complex thermomechanical processing schedules, involving usually several forging...

Renewable energy sources are developed worldwide due to high oil prices and to limit greenhouse gas emissions. In this context, some groups have focused their work on...

A material exhibits a thixotropic behaviour if its apparent viscosity decreases in time under stress, and if it progressively recovers its initial viscosity when the...

This paper evaluates the applicability of different shifting techniques for constructing complex modulus master curves using the time-temperature superposition...

The thermomechanical behavior of bituminous materials and the durability of the asphalt-aggregate interface are key factors to predict pavement damage. This thesis...

Polymacromonomers (PMs) are well-defined branched polymers resulting from macromonomer polymerisation. The PM investigated in this work have been prepared using...

Triumfetta cordifolia and Bridelia thermifolia are two shrubs of tropical Africa whose gums extracted from fresh or dried barks are confined to traditional uses,...

The objective of this PhD work is to provide a systematic and detailed study of the properties of PLA and PHA blends prepared by melt mixing. In particular, the...

This study is directed towards investigating the role of the surface treatment of clay particles on the rheological and thermomechanical behaviour of clayepoxy blends....

The ultimate aim of the present thesis focuses on the structure/processing/properties relationship of the PLA/PBAT materials. The latters are intended for food...

Although being a very promising area of concrete technology, computational modeling of fresh concrete flow is a comprehensive and time consuming task. The complexity...
