The influence of FAs complexity and architectures of cytoskeleton on morphology during cell initial spreading

The FASEB Journal (2012)

Weiyin Lin Ting-Jung Chen Chia-Ching Wu Fong‐Chin Su

The cytoskeleton controls intracellular force equilibrium and force transmission from attachment substrate to focal adhesions (FAs). During epithelial‐mesenchymal transition (EMT), essential process for numerous developmental processes, cell morphology has dramatically change by alter force balance between extracellular matrix (ECM) and cytoskeletons. The force and tension pattern change in cytoskeleton in relation to different morphology is still unknown. Our objective is to simulate the dynamics of intracellular force distribution and total stored energy during cell spreading by using the cytoskeleton tensegrity model with the pre‐tensed actin filaments and the pre‐compressed microtubules. The Madin‐Darby Canine Kidney (MDCK) cell, bovine aortic endothelium cell (BAEC), and myoblastoma cell (C2C12) and NIH 3T3 fibroblast (NIH 3T3) represents each step of EMT. The coordination of FA was used for stimulation. Our results indicated that most of all MDCK and C2C12 is circle shape as compared to BAEC and NIH 3T3 which is polygon. FAs in C2C12 but not BAEC and MDCK fuse together during cell spreading. The total energy in stress fiber and microtubules will increase and decrease with spreading area respectively. Cells have different FA distribution and stress fiber arrangement present different cell morphology due to energy distribution. This study was supported by NSC in Taiwan (NSC 98‐2627‐B‐006‐010).

A simple and unified displacement field for three-dimensional vibration analysis of prestressed circular plates

Journal of Vibration and Control (2012)

Chorng-Fuh Liu Ting-Jung Chen

In this study a simple displacement field is proposed for finite element vibration analysis of circular plates. The displacement field is a combination of a conventional field, which is very popular for three-dimensional vibration analysis of circular plates or cylinders, and another field, which is most general for axisymmetric vibration. The investigation here is intended, through mathematical formulation and examples, to verify the existence of coupled axisymmetric vibration modes. These modes cannot be found by conventional displacement field, but can easily be revealed by the present model. Validity and accuracy of the proposed displacement field to show all the prominent vibration modes of circular plates or cylinder-like structures is also demonstrated by comparing results using the present method with those of a three-dimensional finite element analysis and experiments.

Effect of Preloading-induced Deformation and Stress on Vibration of Circular Plates

Mechanics of Advanced Materials and Structures (2011)

Chorng-Fuh Liu Ting-Jung Chen

The present study presents the effect of deformation and stress due to preloading on vibration of circular plates. The preloadings may be applied in the radial direction on edge or in the transverse direction on plate surface. The research features that, first, a unified displacement field for circular plates is employed; second, the formulation is based on elasticity and has fewer approximations or assumptions than plate theories; third and most noticeable, the analysis takes into account the deformation due to preloading, in addition to the stresses and shows that such deformation has significant effect on vibration of circular plates for some cases.
