Finite element analysis on the stress state of rope hoisting equipment based on the ABAQUS
This paper presents a simulation of the steel wire rope of a certain type hoisting equipment to explore the distributions of stress and deformation in the process of lifting heavy loads. The SolidWorks software was used to establish the 3D solid model of the 6*6+WS structure of stone cross strand wire rope for a certain lifting equipment. Then the solid model of steel wire rope was imported into the ABAQUS directly through the SolidWorks and ABAQUS interface plugin, the material properties were defined, the contact pairs were established, the model was meshed, and the constraints were applied to solve the finite element model. In the normal working range of the wire rope, axial tension of 5000 N was loaded to analyse the stress and deformation distributions. The results show that the stress of wire rope presents a space spiral distribution and the stress of the lateral steel wire of the rope strand is the largest of the steel wire rope, which will provide reference for the design and improvement of the steel wire rope.

Two weddings and a lawsuit: Marriage litigation in fourteenth-century Portugal
Based on one of the few surviving records of marriage cases brought before
 ecclesiastical courts in fourteenth-century Portugal, this article offers a rare
 glimpse of marriage practice in a small village in a remote corner of Western Europe
 and the complex ties that bound its inhabitants and which secular and ecclesiastical
 authorities sought to regulate. Clear parallels can be drawn with the patterns of
 marriage litigation observed in England and Northern France, but evidence also
 suggests that royal legislation played an important part in the resolution of marital
 disputes and in the shaping of conjugal behaviour.
