Variable angle tow laminates (VAT) and stiffeners are known to redistribute the in-plane load distribution tailor buckling mode shapes, respectively, for improving structural performance. To leverage benefits of using VAT in practical applications, present paper, we discuss maximization conducted a stiffened laminated plate with central cutout considering laminate manufacturing constraints. Thr...

BACKGROUND Locking plate fixation of displaced fractures of the proximal humerus is still accompanied by a distinct complication rate, especially in case of osteoporotic bone, short-segment fracture length and comminution of the medial calcar. Secondary loss of reduction leading to varus deformity and screw cutout most frequently lead to surgical revision. The aim of the present study was to ev...

A magnetization vector M imaging using a transmission x-ray microscope with magnetic circular dichroism ~MCD! contrast is demonstrated. MCD images through a semitransparent, 33-nm-thick Fe film are measured at the Fe L3 edge along three different x-ray propagation directions to determine all three components of the M. The transmission images clearly display the vector nature of complex microstr...

We present an x-ray magnetic circular dichroism XMCD study performed at the R L2 edge in RAl2 and RT2 T=Fe,Co intermetallic compounds. By analyzing the modification of the XMCD spectra as both the rare earth and the alloyed element Al, Fe, or Co are changed in the compound, an extra contribution, XMCDT, has been identified and undoubtedly associated with the R 5d -T 3d hybridization in Fe and C...

In this paper, accumulation of plastic deformation of AISI 1045 steel plates with circular cutouts under cyclic axial loading is studied. Loading was applied under force-control conditions. Experimental tests were performed using a Zwick/Roell servo hydraulic machine. Under force-control loading with nonzero mean force, plastic strain was accumulated in continuous cycles called ratcheting. Nume...
