Ti-6Al-2Sn-4Zr-2Mo-0.1Si specimens were shaped by repeated cycles of heating
(to 954 °C) and hammer or press forging followed by a solution anneal that varied from
968 to 998 °C. The coupons were originally extracted from billets forged below the beta
trans us ( 1009 °C) and slow cooled to ambient...
Algorithms for analyzing laser interferometry
signals were developed and adopted to the computer based
processing of small displacement measurements. These
methods, matrix operation approach and fixed parameters
approach, are based on signal phase calculation and are
able to replace complex fringe counting electronic
circuits. The matrix operation provides an approach...
Nailed connections have nonlinear load-displacement
relations. Modeling these connections in an assembled
structure would require a great amount of computational time
because of the large number of degrees of freedom.
Replacing these connections with energetically-equivalent
nonlinear springs reduces the number of degrees of freedom,
and leads to computational efficiency in...
