Specimen test method

A test rig for mechanical load testing of a specimen extending along a longitudinal axis from a first specimen end to a second specimen end and comprising a composite material extending along the longitudinal axis from a first composite end to a second composite end and a primary elongate component extending along the longitudinal axis from a first primary component end to a second primary component end, the first primary component end being the first specimen end, and wherein the composite material encapsulates the primary elongate component along a first interface region extending along the longitudinal axis from the second primary component end to the first composite end,

• wherein the test rig comprises a first connection part adapted to secure the first specimen end, and a second connection part adapted to secure the second specimen end,
• wherein the test rig is operable to apply a load to the specimen by applying a force between the first connection part and the second connection part of the test rig, wherein the force is selected from the group consisting of a compression force, a tension force and a combination thereof, wherein the applied load results in an axial load component and a bending moment being imposed to the specimen,
• wherein the test rig comprises at least a first actuator operable to apply the load to the specimen, and
• wherein the first connection part of the test rig comprises a beam extending between a first beam end and a second beam end, and wherein the first actuator is attached to the first beam end, and wherein the first connection part is adapted to secure the first specimen by securing the first specimen end to an intermediate beam position between the first beam end and the second beam end.

A method for mechanical load testing of a specimen extending along a longitudinal axis from a first specimen end to a second specimen end and comprising a composite material extending along the longitudinal axis from a first composite end to a second composite end and a primary elongate component extending along the longitudinal axis from a first primary component end to a second primary component end, the first primary component end being the first specimen end, and wherein the composite material encapsulates the primary elongate component along a first interface region extending along the longitudinal axis from the second primary component end to the first composite end, wherein the method comprises:

• securing the first specimen end to a first connection part of a test rig;
• securing the second specimen end to a second connection part of the test rig;
• and
• applying a load to the specimen by applying a force between the first connection part and the second connection part of the test rig, wherein the force is selected from the group consisting of a compression force, a tension force and a combination thereof,
• wherein the applied load results in an axial load component and a bending moment being imposed to the specimen, and
• wherein the first connection part of the test rig comprises a beam extending between a first beam end and a second beam end, wherein a first actuator is attached to the first beam end and a second actuator is attached to the second beam end, and wherein securing the first specimen end to the first connection part comprise securing the first specimen end to an intermediate beam position between the first beam end and the second beam end.
