Helium is expected to be present in the ejecta of some hydrogen-poor superluminous supernovae (SLSN-I). However, so far only one event, PTF10hgi has been identified with He features in its photospheric spectra (Quimby et al. 2018). We present the dis

v-p material point method for weakly compressible problems
Autor: Lei Kan, Xinming Qiu, Zhen-Peng Chen, Kam Yim Sze, Xiong Zhang
Publikováno v: Computers & Fluids. 176:170-181
The weakly compressible material point method (WCMPM) suffers from volumetric-locking and numerical oscillation in modeling fluid flow and fluid-structure interaction problems. In this paper, a v-pformulation of the material point method (vp-MPM) is

Coupled Shell-Material Point Method for Bird Strike Simulation
Autor: Bo Wu, Zhen-Peng Chen, Yan Liu, Yanping Lian, Xiong Zhang
Publikováno v: Acta Mechanica Solida Sinica. 31:1-18
In a bird strike, the bird undergoes large deformation like flows; while most part of the structure is in small deformation, the region near the impact point may experience large deformations, even fail. This paper develops a coupled shell-material p

A frictional contact algorithm for implicit material point method
Autor: Xinming Qiu, Zhen-Peng Chen, Yan Liu, Xiong Zhang
Publikováno v: Computer Methods in Applied Mechanics and Engineering. 321:124-144
The explicit material point method (MPM) works successfully in modeling high frequency problems, but it is very computationally expensive in simulating low frequency with small time steps or quasi-static problems. Thus, several groups have developed

Improved coupling of finite element method with material point method based on a particle-to-surface contact algorithm
Autor: Xinming Qiu, Zhen-Peng Chen, Xiong Zhang, Yanping Lian
Publikováno v: Computer Methods in Applied Mechanics and Engineering. 293:1-19
For extreme deformation problems, material point method (MPM) takes competitive advantages compared with finite element method (FEM) which often encounters mesh distortion. However, for small deformation problems, FEM is still more efficient and accu

NEW ASTROPHYSICAL REACTION RATE FOR THE 12 C( α , γ ) 16 O REACTION
Autor: Yong-Jiang Li, Zhen-Peng Chen, Ye-Ying Sun, G.T. Fan, Yu-Gang Ma, Zhen-Dong An
Publikováno v: The Astrophysical Journal. 817:L5
A new astrophysical reaction rate for C-12(alpha, gamma)O-16 has been evaluated on the basis of a global R-matrix fitting to the available experimental data. The reaction rates of C-12(alpha, gamma)O-16 for stellar temperatures between 0.04
