At present, scholars have put forward a lot of strength models about metal materials at high strain rate.
For a lot of metal materials, the description of deformation is quite accurate with J-C strength model.

Introduction Ultimate axisymmetric punching capacity of concrete slabs are problems related to the three dimensional stress state analysis and the failure properties of the brittle materials.
Among them, the twin-shear failure criterion has abilities to reflect the failure properties for all kinds of materials and take the other existing criteria as its one special case [3, 4].
Hill [20] had pointed out that the Harr-Von Karman’s perfect plastic assumption is not inconsistent with the materials.

The paper is generally focused on the determination and evaluation of yield and ultimate strengths of structural steels, not only current materials but also materials of existing steel structures when the properties are unknown and no material certificates exist.
Design, Characteristic and Nominal Value of Material Property According to the rules given by European Standards for the design of civil engineering structures [5], [7], the strength values used in the process of the structural and static design are given by characteristic and design values in the case of most materials, that means, for example, concrete, cement composites, masonry, timber, ceramics or other similar materials.
