Abstract
A fixture for testing a tubular member simultaneously in bending and torsion is disclosed. The fixture includes first and second attachment elements that are configured to couple to the tubular member, and a load shoe that is configured to fit within the tubular member. The load shoe includes a body having a contact surface configured to contact a portion of an internal surface of the tubular member and at least one load reaction strut coupled to the body. The load reaction strut is configured to pass through a hole in the tubular member and accept a first force applied in a first direction that is perpendicular to an axis of symmetry of the tubular member.
Claims15
A fixture for testing a tubular member, the fixture comprising:
- first and second attachment elements configured to couple to the tubular member;
- a load shoe configured to fit within the tubular member, the load shoe comprising:
- a body having a contact surface configured to contact a portion of an internal surface of the tubular member;
- and
- at least one load reaction strut coupled to the body, the load reaction strut configured to pass through a hole in the tubular member and accept a first force applied in a first direction that is perpendicular to an axis of symmetry of the tubular member.
A load shoe for applying a lateral load to a tubular member, the load shoe comprising:
- a body having a contact surface configured to contact a portion of an internal surface of the tubular member;
- and
- at least one load reaction strut coupled to the body, the load reaction strut configured to pass through a hole in the tubular member and accept a first force applied in a first direction that is perpendicular to an axis of symmetry of the tubular member.
A method of apply a lateral load to a tubular member, the method comprising the steps of:
- placing a load shoe comprising a contact surface configured to contact a portion of an internal surface of the tubular member and at least one load reaction strut configured to pass through a hole in the tubular member within the tubular member such that the at least one load reaction strut extends through a hole in the tubular member;
- and
- applying the lateral load to the at least one load reaction strut.
