是的，ABAQUS可以编写一维子例程。以下是一维子例程的代码示例：

1D subroutine subroutine.f：

  subroutine UMAT(STRES,STATEV,DSTRAN,TIME,DTSTEP,SUBST,NSUBST,NFIELD, 
 +        NPROPS,COORDS,U,DUDDT,DFIELD,PROPS)

C implicit double precision (a-h,o-z) C dimension STRES(6),STATEV(1),DSTRAN(6),SUBST(NSUBST), + DFDSTR(6,NFIELD),DFIELD(NFIELD),PROPS(NPROPS),COORDS(3) C C Code: C C Call the user-defined materials routine for a 1D material C CALL USRMAT1D(STRES, STATEV, DSTRAN, TIME, DTSTEP, SUBST, NSUBST, + NFIELD, NPROPS, COORDS(1), U, DFDSTR, DFIELD, PROPS) C RETURN END

在主程序中调用子例程：

*USER SUBROUTINE, FILE = "subroutine.f" *DIMENSION UMAT(6) *EL FILE *EL PRINT, FREQUENCY=1 *STEP *USER MATERIAL, TYPE=USER, UNSYMM=NO 1D, DENSITY=TABULAR, DATABANK='density', DIRECTION=1 *USER OUTPUT, FIELD=STATUS, FREQUENCY=1 *USER OUTPUT, FIELD=STRESS, FREQUENCY=1 *SHELL SECTION, ELSET=EALL, MATERIAL=USER1 *SOLID SECTION, ELSET=EALL, MATERIAL=USER1 *NODE FILE, OUTPUT=FULL *EL FILE, OUTPUT=FULL *END STEP

这是一个基础的一维材料子例程的示例，可以根据需要进行调整。当然，如果用户具有ABAQUS的使用经验，则可以根据需要修改主程序。
