Structural Mechanics and Thermal Stressesx

Determination of Constitutive Properties Using DIC-Displacement Data and U-FEM

A. Alshaya [1], R. Bourisli [1], J. Considine [2],
[1] Kuwait University, Kuwait
[2] Forest Products Laboratory, Madison, WI, US

The constitutive properties of a paperboard side-notched composite loaded vertically were determined in inverse method (IM) using a single component of measured displacement data. The cost function, which is the difference between the measured v-displacement and the reconstructed ... Per saperne di più

Design of a Mechanical Resonant Station to Free Jammed Micro-Mechanisms

L. Spicci [1],
[1] Everywave srl, Italy

Some types of mechanical devices, such as molds, but not only, include a large number of micro-mechanisms, valves, channels, vents, or other devices subject to deterioration or malfunctioning, frequently caused by unwelcome phenomena such as incrustations, fillings, or reciprocal bonding ...
