Web2 days ago · Figure 2 a shows a simulated tensile test of the film at different relaxation stages after being irradiated. The film reaches its ultimate tensile strength (UTS) when the strain reaches the critical strain of approximately 0.05∼0.06. The critical strain increases slightly with increase of the relaxation time. WebHere are some tests that we used for determining the Tensile strength of the concrete.. 1.
