call SPRINC(STRESS,PS,LSTR,NDI,NSHR)是abaqus内置的子程序吗?

最近看《abaqus在岩土工程中的应用》一书,里面讲用户自定义材料二次开发里边有这么一句:
call SPRINC(STRESS,PS,1,3,3)
但是我在后文中没有找到subroutine SPRINC()
请问SPRINC这个子程序是abaqus内部默认某个含义的吗?

CALL SPRINC(BBAR, BBARP, BBARN, 1, NDI, NSHR)
– Tensor BBAR consists of NDI direct components and NSHR shear
components.
– SPRINC returns the principal values and direction cosines of the
principal directions of BBAR in BBARP and BBARN, respectively.
– A value of 1 is used as the fourth argument to indicate that BBAR
contains stresses. (A value of 2 is used for strains.)
