Temperature and strain-rate dependence of yield stress of polyethylene

Effect of sol–gel derived nano-silica and organic peroxide on the thermal and mechanical properties of low-density polyethylene/wood flour composites

“…The WF containing composites show a distinct two-step degradation. The first step is found in the range of 300e400 C and is attributed to the decomposition of the lignocellulosic material in the composites [28]. The second step indicates the degradation of LDPE.…”

High velocity impact and armour design

“…The fibre modulus is assumed constant and has been taken from the open literature [8]. The introduction of rate and temperature effects [11][12][13] into the model can also be achieved, however, a relationship between rate and temperature needs to be developed as does a technique to determine adiabatic heating effects, and the corresponding change in stiffness, strength and fracture energy.…”

Yielding of polyethylene through propagation of chain twist defects: Temperature, stem length and strain-rate dependence

“…The dislocation core radius obtained by computer simulations is r 0 Z1 nm [15]. The expression for the shear modulus K (MPa) as a function of temperature is taken from Brooks et al [16]:…”
