    Black and white image of 16 unidentified men and one man identified as ""Dick"" standing second from left, all posed in front of a saloon, DickLee's Cave Saloon. Image mounted on dark gray matte board. Verso: Written in pencil; ""Dick is second man from left- hands in pocket. P. A. saloon.""Contributor Mabel Prager (donation first gifted in 1975) wrote a short biography about her family: Mrs. Prager identified her grandfather as Richard ""Dick"" R. Lee who migrated to the United States in 1885 or 86 from Cornwall, England; thus carried the identity as a ""Cousin Jack"" as many Cornishmen who migrated to the U. S. were called. Mr. Lee settled in Pinos Altos, N. M. and eventually moved his family from England around 1891 to Pinos Altos. The mine near Pinos Altos that Mr. Lee worked closed, and the Lee family then moved to Mogollon, N. M. Later, Mr. Lee was involved in a severe mining accident and the family moved back to Pinos Altos, opening a bar known as ""Dick's Cave"" and a feed and grain store. Mrs. Prager wrote that the building (the old bar) is still in existence.

    Visco-elastic regularization and strain softening

    No full text
    In this paper it is intended to verify the capacity of regularization of the numerical solution of an elasto-plastic problem with linear strain softening. The finite element method with a displacement approach is used. Drucker-Prager yield criteria is considered. The radial return method is used for the integration of the elasto-plastic constitutive relations. An elastovisco- plastic scheme is used to regularize the numerical solution. Two constitutive laws have been developed and implemented in a FE-program, the first represent the radial return method applied to Drucker-Prager yield criteria and the second is a time integration procedure for the Maxwell visco-elastic model. Attention is paid to finite deformations. An associative plastic flow is considered in the Drucker-Prager elasto-plastic model. The algorithms are tested in two problems with softening. Figures showing the capability of the algorithms to regularize the solution are presented
