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.

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.
