This paper describes a new test technique for determining the tensile strength of concrete. In this test, a concrete cylinder (or cube) specimen is placed vertically between the loading platens of_a testing machine and compressed by two steel punches located concentrically on the top and bottom surfaces of the cylinder (or cube) . The relevant formula for computing the tensil,e strength in the new test is herein developed using the theory of perfect plasticity. It is shown that the necessary test arrangement, as well as the formula for computing the tensile strength of concrete, are very simple. The new test appears promising for practical use. * Assistant Professor, Fritz Engineering Laboratory, Department of Civil Engineering, Lehigh University, Bethlehem, Pennsylvania.read more

Double Punch Test to control the energy dissipation in tension of FRC (Barcelona test)
TL;DR: In this article, the Double Punch Test (DPT) has been recovered for the quality control of the tension behavior of fiber reinforced concrete (FRC) and a reduction of the scatter in the values of the tensile strength and of the toughness.

Comments on an indirect tensile test on concrete cylinders
TL;DR: The tensile strength of concrete is measured by applying a compressive load to opposite generators of a cylindrical specimen as discussed by the authors, where the load is applied along the diametral plane containing the load.

TL;DR: In this article, the limit theorems of the generalized theory of perfect plasticity were applied to obtain bearing capacity in two dimensions (strip loading or rigid punch) and in three dimensions (circular and square punches).

Stress distribution in splitting tests

TL;DR: In this paper, a comparative analysis of the impact of different types of straddling stresses on line-lading is presented, and it is concluded that SPECIMENS (1), (2) and (3) have SIMILAR DISTRIBUTION PATTERNS of TENSILE STRESS, and the CUBE SPLITTING TESTS (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) have similar effects.
