关于混凝土非常全面的资料，理论和k文件很齐全（如果只是想要k文件对理论不想了解，直接到http://ftp.lstc.com/anonymous/outgoing/jday/concrete 这个链接）

下面列出一些关于混凝土材料MAT_016, MAT_072, MAT_084, MAT_096的一些参考资料：

GENERAL
Malvar, L.J., D. Simons, "Concrete Material Modeling in Explicit Computations," Workshop on Recent Advances in Computational Structural Dynamics and High Performance Computing, USAE Waterways Experiment Station, April 24-26, 1996. (http://ftp.lstc.com/anonymous/ou ... ete.CP27_WES96K.pdf)

MAT_016
Pseudo_Tensor model:
Burton, D.E., Lettis, L.A., Bryan, J.B.,  and Frary. N.R., "Physics and Numerics of the Tensor Code," Lawrence Livermore National Laboratory, Internal Document, UCID-19428, July ,1982.

MAT_072
Concrete_Damage model:
Malvar, L.J., J.E. Crawford, J.W. Wesevich, and D. Simons, "A Plasticity Concrete Material Model for DYNA3D," International Journal of Impact Engineering, Volume 19, Numbers 9-10, pages 847-873, 1997. [From the mat_072 source code comments... "This material nodel is based on the work Malvar, Crawford and Wesevich.  See Defense Nuclear Agency report DNA001-91-C-0059."]

The following paper is a very recent update to MAT_072:
Schwer, L.E., and Malvar, L.J., "Simplified Concrete Modeling with *MAT_CONCRETE_DAMAGE_REL3," 4th German LS-DYNA Forum, Bamberg, Germany, October, 2005. (http://ftp.lstc.com/anonymous/ou ... crete/mat_072r3.pdf  or http://www.dynamore.de/download/af05/papers/H-I-49.pdf)

You also might find the following paper of interest which uses both MAT_016 and MAT_072:
Yonten, K., Manzari, M.T., Eskandarian, A., and Marzougui, D., "An Evaluation of Constitutive Models of Concrete in LS-DYNA Finite Element Code," 15th ASCE Engineering Mechanics Conference, New York, June, 2002.
http://www.civil.columbia.edu/em2002/proceedings/papers/196.pdf
I believe the reinforcement model for MAT_072 is the same as that for MAT_016 which is briefly described on page 20.72 of the LS-DYNA Version 970 User's Manual.

MAT_084
Winfrith_Concrete model.
The last two are available in http://ftp.lstc.com/anonymous/outgoing/jday/concrete (see Winfrith*.pdf)
Ottosen, N.S., "A Failure Criterion for Concrete," Journal of the Engineering Mechanics Division, Volume. 103, Number 4, pages 527-535, July/August, 1977.
Broadhouse, B.J., "DRASTIC - A Computer Code for Dynamic Anaylsis of Stress Transients in Reinforced Concrete," Safety and Engineering Science Division, United Kingdom Atomic Energy Authority, Winfrith, AEEW-R 2124, 1986.
Broadhouse, B.J. and Neilson, A.J., "Modelling Reinforced Concrete Structures in DYNA3D,"  Safety and Engineering Science Division, United Kingdom Atomic Energy Authority, Winfrith, AEEW-M 2465, October, 1987.  Paper presented at DYNA3D User Group Conference, London, September, 1987.
Broadhouse, B.J., "The Winfrith Concrete Model in LS-DYNA3D," Safety Performance Department, Atomic Energy Authority Technology, Winfrith, SPD/D(95)363, February, 1995.
A recent paper using the reinforced option:

http://www.dynalook.com/document ... iques_I/Algaard.pdf 好像打不开了，我更新网址为 http://www.dynalook.com/european-conf-2005/Algaard.pdf

MAT_096
Brittle-Damage model:

Govindjee, S., Kay, G.J., and Simo, J.C., "Anisotropic Modelling and Numerical Simulation of Brittle Damage in Concrete," International Journal for Numerical Methods in Engineering, Volume 38, pages 3611-3633, 1995.
