CRACKED COLUMNS UNDER COMPRESSION FIXED ENDS

THE DEFLECTION, THE LOAD CARRYING CAPACITY, THE STRESS INTENSITY FACTOR, AND THE FRACTURE LOAD OF A SLENDER COLUMN WITH FIXED ENDS HAVE BEEN CALCULATED. THE COLUMN HAS A SINGLE-EDGE CRACK AT THE MID-SECTION AND IT HAS AN INITIAL DEFLECTION. A CRACK REDUCES THE FLEXURAL RIGIDITY OF A COLUMN. IT INCREASES THE LATERAL DEFLECTION AND DECREASES THE LOAD CARRYING CAPACITY OF A COLUMN. THE LATERAL DEFLECTION AT THE CRACKED SECTION INCREASES THE BENDING MOMENT THERE; THEREBY, IT INCREASES THE STRESS INTENSITY FACTOR AND DECREASES THE FRACTURE LOAD. /AUTHOR/
