Article
Assignment of natural frequencies by an added mass and one or more springs
(2004)The problem of assigning natural frequencies to a multidegreeoffreedom undamped system by an added mass connected by one or more springs is addressed. The added mass and stiffnesses are determined using receptances from ...

Article
Cell adhesion and matrix stiffness: Coordinating cancer cell invasion and metastasis
(2018)Metastasis is a multistep process in which tumor extracellular matrix (ECM) and cancer cell cytoskeleton interactions are pivotal. ECM is connected, through integrins, to the cell's adhesome at cellECM adhesion sites and ...

Article
Estimation of rotational frequency responses
(2003)Rotational frequency response functions are potentially valuable for structural damage detection but are difficult to obtain because of the practical problems of applying a pure moment. In the literature various indirect ...

Article
Exploring the nanosurface of collagenous and other fibrotic tissues with AFM
(2017)Atomic force microscope (AFM) is a powerful and invaluable tool for imaging and probing the mechanical properties of biological samples at the nanometric scale. The importance of nanoscale characterization and nanomechanics ...

Article
An inverse method to assign receptances by using classical vibration absorbers
(2009)The classical massspring absorber can be thought of as a very simple structural modification. In this paper the inverse problem of assigning receptances to a dynamic system by using one or more simple massspring absorbers ...

Article
Regional elastic modulus measurements of the exvivo murine heart using atomic force microscopy
(2013)Stiffness is an important mechanical index for characterisation of human and animal cells, tissues and intact organs. This study presents efforts for passive mechanical characterisation of the exvivo C57BL/6 murine heart ...

Article
Seismic Rehabilitation of Substandard R.C. Buildings with Masonry Infills
(2018)Seismic deformation demands are localized in areas of stiffness discontinuity, such as in the soft storys of frame structures, where disproportionate damage is often reported in postearthquake reconnaissance. In many parts ...

Article
Spatial distribution of Winkler spring stiffness for rectangular mat foundation analysis
(2017)Structural design of mat foundations of buildings is often done by performing static analysis of a slab resting on vertical uncoupled Winkler springs. It is already well established that the simplifying assumption of a ...

Article
Structural modification. Part 1: Rotational receptances
(2005)The inverse problem of assigning natural frequencies and antiresonances by a modification to the stiffness, mass and damping of a structure is addressed. Very simple modifications such as the addition of masses and grounded ...

Article
Structural modification. Part 2: Assignment of natural frequencies and antiresonances by an added beam
(2005)In this paper the inverse structural modification problem is solved in order to determine the dimensions of the crosssection of a beam that when added to an original structure will assign natural frequencies or antiresonances ...
