In this paper,the node based smoothed-strain Abaqus user element(UEL)in the framework of finite element method is *** basic idea behind of the node based smoothed finite element(NSFEM)is that finite element cells are divided into subcells and subcells construct the smoothing domain associated with each node of a finite element cell[Liu,Dai and Nguyen-Thoi(2007)].Therefore,the numerical integration is globally performed over smoothing *** is demonstrated that the proposed UEL retains all the advantages of the NSFEM,i.e.,upper bound solution,overly soft stiffness and free from locking in compressible and nearly-incompressible *** this work,the constant strain triangular(cST)elements are used to construct node based smoothing domains,since any complex two dimensional domains can be discretized using cST *** additional challenge is successfully addressed in this *** efficacy and robustness of the proposed work is obtained by several benchmark problems in both linear and nonlinear *** developed UEL and the associated files can be downloaded from https://***/nsundar/NSFEM.

Ⅰ. Introduction The graptolites described in the present paper were collected by Profs. Y. Wang, A. ***, W. T. chang and others from the Lower Ordovician Dawan formation of the Ichang-Tzekueiarea, western Hupeh during 1956-1957 and by Messrs. W. N. lee, S. S. chang and thewriter from the Dawan formation of the Makiang district, southern kueichou in the springof 1959. More than twenty species belonging to 10 genera are recognized. Among them fourspecies and varities are new. The writer wishes to express his indebtedness to Prof. A. T. Mu for instruction and criticalreading of the manuscript.

The global incidence rates of in-hospital cardiac arrest(IHcA)range from1.2 to 9.0 per1,000 hospitalized patients,as per the National cardiac Arrest Database.[1] While IHcAs tend to exhibit superior 30-day survival rates relative to out-of-hospital cardiac arrests (OHcA) due to situational advantages,such as immediate access to medical personnel and treatments.
