1. A tensile bar, comprising:
a first support structure configured for attachment to a downhole string for a wellbore, the first support structure having a longitudinal axis and presenting a first engagement face that crosses the longitudinal axis of the first support structure, the first engagement face having a peripheral surface that is spaced from the longitudinal axis of the first support structure;
a second support structure having a longitudinal axis and presenting a second engagement face that crosses the longitudinal axis of the second support structure, the second engagement face having a peripheral surface that is spaced from the longitudinal axis of the second support structure, the second support structure spaced from the first support structure; and
a plurality of tensile members extending between the first engagement face and the second engagement face, each member of the plurality of members extending at least in part in a direction other than longitudinally axially of the tensile bar, each member of the plurality of tensile members extending from a first point on the first engagement face to a second point on the second engagement face, a line between the first point and the second point for each member being parallel to a longitudinal axis of the tensile bar, wherein the plurality of tensile members are configured to fail during use in the wellbore in order to protect the downhole string.
