Many materials under multiaxial periodic loading exhibit rate-independent internal dissipation per cycle. Constitutive modelling for such dissipation under spatially variable triaxial stresses is ...

During the ANSYS Conference & 28 th CADFEM User’s Meeting held 2010 in Aachen, Germany, a new approach was presented, which facilitates the integration of experimental modal analysis test into the CAE ...

Multi-story buildings are assembled over-cautiously to withstand wind strengths, researchers have found. Multi-storey buildings are assembled over cautiously to withstand wind strengths, researchers ...

Modal data deals with the dynamic properties of a structure and can help in the design of almost any structure, facilitating to detect areas where design changes are required. Determining the ...

Theoretical development of a dynamic stiffness matrix (DSM) based direct damping matrix identification method is revisited in this paper. This method was proposed to identify both the mechanism and ...

When in doubt, make it stout. That was the rule of thumb for designing strong and durable machine tools in the past. Over the years, however, this mindset has changed as technical advances have ...

Aircraft structures are prone to vibrations due to their lightweight construction. In most cases, these vibrations are not critical. They decay due to damping effects from aerodynamic forces and ...
