Journal ArticleDOI
Size Effect on Biaxial Flexural Strength of Concrete
TL;DR: In this paper, the size effect on the tensile strength of concrete is investigated experimentally for the case of equi-biaxial tension, and the analysis leads to a deterministic Type I size effect.
Journal ArticleDOI
Evaluation of earthquake deformation and performance for RC bridge piers
TL;DR: In this article, a hysteretic shear-axial interaction model is presented to represent the shear stiffness transitions due to axial force variation and is implemented in a nonlinear finite element program.
Journal ArticleDOI
Interfacial shear stress optimization in sandwich beams with polymeric core using non-uniform distribution of reinforcing ingredients
Hamid Ghasemi,Pierre Kerfriden,Stéphane Bordas,Jacob Muthu,Goangseup Zi,Timon Rabczuk,Timon Rabczuk +6 more
TL;DR: In this article, a non-uniform rational B-spline (NURBS) based reinforcement distribution optimizer is developed to minimize the local stress minimization within any arbitrary zone of the design domain.
Journal ArticleDOI
Stretchable array of CdSe/ZnS quantum-dot light emitting diodes for visual display of bio-signals
Yonghui Lee,Dong Sik Kim,Sang Woo Jin,Hanchan Lee,Yu Ra Jeong,Ilhwan You,Goangseup Zi,Jeong Sook Ha +7 more
TL;DR: In this article, a stretchable array of CdSe/ZnS QD-LEDs is fabricated on a rigid NOA63 islands and electrically connected using liquid metal Galinstan interconnections.
Journal ArticleDOI
A simple circular cell method for multilevel finite element analysis
TL;DR: A simple multiscale analysis framework for heterogeneous solids based on a computational homogenization technique is presented and is applied to several standard examples to show its accuracy and consistency of the method proposed.
