Eps elastic inclusion

WebDec 23, 2016 · A nonlinear elastic–plastic hardening model is first established for three different EPS geofoam densities. The model takes advantage of the standard compression tests usually performed by the manufacturer to extract essential plasticity data that allows for the behavior to be numerically simulated. WebAug 16, 2024 · This research will focus on developing specific testing procedures that are relevant to this problem. Long-term mechanical properties of different EPS materials under cyclic load applications will be investigated in detail. Based on the results obtained from these tests, elastic inclusion design recommendations for integral bridges will be ...

Numerical modeling of EPS seismic buffer shaking table tests

WebMar 3, 2013 · Today, the choice for the compressible inclusion is block-moulded low-density EPS, or EPS “geofoam” according to modern geosynthetics terminology. ... quantity of interest to attenuate dynamic loads is the buffer stiffness introduced earlier and defined as the ratio of EPS elastic Young’s modulus to EPS thickness. Webthe inclusion and the matrix have the same elastic constants. The eigenstress is defined as σ ∗ ij ≡ C ijkle kl. In reality, the inclusion is surrounded by the matrix. Therefore, it is not able to reach the state of eigenstrain and zero stress. Instead, both the inclusion and the matrix will deform and experience an elastic stress field.
