Experimental Study on Mechanical Properties and Failure ...

Based on biaxial tension-compression failure criteria and octahedral stress space failure criteria from the literature, two different failure criteria were proposed. Analysis of the failure mechanism indicated that the water:cement ratio (w/c) and material compactness have a greater effect on

A numerical study of various plastically unstable ...

Various types of behavior due to plastic instability under uniaxial tension and compression are numerically investigated regarding sheet materials, plane strain blocks, and cylindrical bars and hollow cylinders. The code GOLDA for analysis of large elastic-plastic deformation previously developed by the author is used, which is one of quasi-static explicit FEM programs. Both of diffuse type ...

Study on the influence of orthotropy and tension ...

2018-7-1  Most yield criteria possess a point-symmetry with respect to its center, meaning that a stress state and its reverse state have the same absolute value. However, this can be an unrealistic approximation, even for cubic metals (both face-centered cubic and body center cubic)), which can present a small asymmetry between the yield stress in tension and compression, i.e. a strength

Study on the mechanical behaviors and failure mechanism

2021-12-1  The brittle nature of concrete limits the further development, while the addition of polymer can enhance the toughness and improve the working performance. Understanding the mechanical properties and failure mode of polyurethane cement composites (PUCC) is of great significance in the field of construction engineering. To solve these issues, in this paper, the tensile and compressive ...

Study on Plastic Response Under Biaxial Tension and Its ...

2020-2-25  The mechanical response and microstructural changes under biaxial tension of two magnesium alloy sheets, ZE10 and AZ31, have been investigated. The forming limit diagram (FLD) of the two alloys was further assessed using the Marciniak–Kuczynski (M–K) model combined with two constitutive models: (a) crystal plasticity finite element (CPFE), and (b) phenomenological yield. The
