On Maximum Fillet Stresses in Breech Ring.

Abstract

The effect of fillet geometry and wall thickness on maximum fillet stresses was investigated in the 105mm M137 Howitzer breech ring. The NASTRAN finite element analysis of three fillet geometries and two wall thicknesses shows that an elliptical fillet is preferred. A limited two-dimensional photoelastic experiment substantiated analytical findings. For the purpose of optimizing the combination of fillet geometry and wall thickness, a thorough photoelastic investigation is desirable. (Author)
