Present Situation and Future Prospects of Child Restraint Systems for Vehicles

Fang Yuan,Wu Guangqiang

Strategic Study of CAE 2006, Volume 8, Issue 8, Pages 81-85

Abstract:

Child restraint system(CRS)is a new study field in the world. Especially in China, the CRS research is particularly meaningful with the rapid growth of the number of child passengers. The amendment and optimization on the regulations of CRS are brought out based on the distinction between CRS and occupant safety systems. The application of advanced design theory, the technology of computer simulation and the systematical analysis strategy will bring a new prospect for the development of CRS.

Finite element analysis of stress concentrations and failure criteria in composite plates with circular

Abdelhak KHECHAI,Abdelouahab TATI,Abdelhamid GUETTALA

Frontiers of Mechanical Engineering 2014, Volume 9, Issue 3, Pages 281-294 doi: 10.1007/s11465-014-0307-9

Abstract:

In this study, the stress concentration factors (SCF) in cross-and-angle-ply laminated composite plates as well as in isotropic plates with single circular holes subjected to uniaxial loading is studied. A quadrilateral finite element of four-node with 32 degrees of freedom at each node, previously developed for the bending and mechanical buckling of laminated composite plates, is used to evaluate the stress distribution in laminated composite plates with central circular holes. Based up on the classical plate theory, the present finite element is a combination of a linear isoparametric membrane element and a high precision rectangular Hermitian element. The numerical results obtained by the present element compare favorably with those obtained by the analytic approaches published in literature. It is observed that the obtained results are very close to the reference results, which demonstrates the accuracy of the present element. Additionally, to determine the first ply failure (FPF) of laminated plate, several failure criterions are employed. Finally, to show the effect of ratio on the failure of plates, a number of figures are given for different fiber orientation angles.

Bile duct injury repair — earlier is not better

Vinay K. Kapoor

Frontiers of Medicine 2015, Volume 9, Issue 4, Pages 508-511 doi: 10.1007/s11684-015-0418-7

Abstract:

Bile duct injury is a common complication of cholecystectomy.The timing of bile duct injury repair remains controversial.Most patients with bile duct injury present with bile leak and sepsis; thus, early repair is not recommendedendoscopic stenting are the mainstays of treatment of bile leak because they convert acute bile duct injury

Concepts and implementation of strain-based criteria in design codes for steel structures

Reidar BJORHOVDE

Frontiers of Structural and Civil Engineering 2012, Volume 6, Issue 3, Pages 210-216 doi: 10.1007/s11709-012-0165-7

Abstract: A uniaxial tension test is commonly used to determine the mechanical properties of steel, but it has no meaning for the response of the material in a structure. The test was developed as a consensus solution by producers, fabricators, designers and code writers, to have a standard by which similar materials could be compared to a common base. It does not represent the actual behavior of the steel in a structure, and was never intended to do so. To study the true behavior of the structure and how the material responds it would be better to determine the strains and deformations that will take place during actual service condition. Such characteristics reflect the real behavior, whether in the elastic or inelastic range. If stresses or forces are needed, these are easily determined by the value of the strain and the relevant material modulus, along with the type of cross section, whether elastic or inelastic. The paper addresses the properties of a range of structural steels, how these are incorporated into design standards and how the standards define deformation characteristics and demands for bolted and welded connections.

Progress and perspectives of neural tissue engineering

Xiaosong Gu

Frontiers of Medicine 2015, Volume 9, Issue 4, Pages 401-411 doi: 10.1007/s11684-015-0415-x

Abstract:

Traumatic injuries to the nervous system lead to a common clinical problem with a quite high incidence and affect the patient’s quality of life. Based on a major challenge not yet addressed by current therapeutic interventions for these diseases, a novel promising field of neural tissue engineering has emerged, grown, and attracted increasing interest. This review provides a brief summary of the recent progress in the field, especially in combination with the research experience of the author’s group. Several important aspects related to tissue engineered nerves, including the theory on their construction, translation into the clinic, improvements in fabrication technologies, and the formation of a regenerative environment, are delineated and discussed. Furthermore, potential research directions for the future development of neural tissue engineering are suggested.
