| 1 | Evaluation of stress intensity factors for bi-material interface cracks using displacement jump methods显示文摘The aim of the present work is to investigate the numerical modeling of interfacial cracks that may appear at the interface between two isotropic elastic materials. The extended finite element method is employed to analyze brittle and bi-material interfacial fatigue crack growth by computing the mixed mode stress intensity factors(SIF). Three different approaches are introduced to compute the SIFs. In the first one, mixed mode SIF is deduced from the computation of the contour integral as per the classical J-integral method,whereas a displacement method is used to evaluate the SIF by using either one or two displacement jumps located along the crack path in the second and third approaches. The displacement jump method is rather classical for mono-materials,but has to our knowledge not been used up to now for a bimaterial. Hence, use of displacement jump for characterizing bi-material cracks constitutes the main contribution of the present study. Several benchmark tests including parametric studies are performed to show the effectiveness of these computational methodologies for SIF considering static and fatigue problems of bi-material structures. It is found that results based on the displacement jump methods are in a very good agreement with those of exact solutions, such as for the J-integral method, but with a larger domain of applicability and a better numerical efficiency(less time consuming and less spurious boundary effect). | K.

| 9 | Recent advances in chemically defined and tunable hydrogel platforms for organoid culture显示文摘Recent developments in organoid culture technologies have made it possible to closely recapitulate intrinsic characteristics of different tissues under in vitro conditions.These organoids act as a translational bridge between the traditional 2D/3D cultures and the in vivo models for studying the tissue development processes,disease modeling,and drug screening.Matrigel and tissue-specific extracellular matrix have been shown to support organoid development,efficiently;however,their chemically undefined nature,non-tunable properties,and associated batch-to-batch variations often limit reproducibility of the assembly process.In this regard,chemically defined platforms offer wider opportunities to optimize and recreate tissue-specific microenvironment.The present review delineates the current research trends in this sphere,focusing on material perspective and the target tissues(e.g.,neural,liver,pancreatic,renal,and intestinal).The review winds up with a discussion on the current limitations and future perspective to provide a basis for future research. | Tarun Agarwal Nehar Celikkin Marco Costantini Tapas K.Maiti Pooyan Makvandi | 2021 | Bio-Design and Manufacturing2021，4，3： | 1 |
