Methods of and apparatus for testing a material are described. The testing involves providing a material across a region of a support member which is arranged to define an opening which is closed by a plug means having a surface in contact with the material that is substantially coplanar with the region. The material is adhered to the region of the support member. A force applying means is moved relative to the material to apply a force to said material through the intermediary of the plug means, which does not substantially deform under the application of the force.
