ble strap are the best joint designs to resist bending forces. Unfortu-
nately, they both require expensive machining.

3.5.2 Stiffening joints and other methods
of reducing peel stress
When thin members are bonded to thicker sheets, operating loads gen-
erally tend to peel the thin member from its base, as shown in Fig.
3.14 (top). The subsequent illustrations show what can be done to
decrease peeling tendencies in simple joints.
Often thin sheets of a material are made more rigid by bonding
stiffening members to the sheet. When such sheets are flexed, the
