A. Tafreshi et Te. Thorpe, NUMERICAL-ANALYSIS OF STRESSES AT OBLIQUE HOLES IN PLATES SUBJECTED TO TENSION AND BENDING, Journal of strain analysis for engineering design, 30(4), 1995, pp. 317-323
Stress analysis of a series of thick, wide, flat plates with oblique h
oles subjected to uniaxial tension and out-of-plane bending has been c
arried out using the finite element method (FEM), and in some cases th
e boundary element method (BEM). Different plate thickness-hole diamet
er ratios, angles of hole obliquity and orientation have been consider
ed to provide stress concentration factors at such holes. The work cov
ers plate thickness-hole diameter ratios from 1.3 to 3.0, hole obliqui
ty angles from 0 to 60 degrees and orientation of the major axis of th
e surface ellipse relative to the applied load direction of 9 to 90 de
grees. The results for uniaxial tension have been compared with those
determined using the photoelastic frozen-stress technique in order to
verify the finite element models before proceeding to the bending case
s, which provide new data.
