It is challenging to predict the material degradation and crack initiation of short fiber reinforced thermoplastics (SFRT) components with high computation efficiency and low parameter identification effort. To achieve that, this work utilizes a hybr

Under fatigue-loading, short-fiber reinforced thermoplastic materials typically show a progressive degradation of the stiffness tensor. The stiffness degradation prior to failure is of primary interest from an engineering perspective, as it determine

Under fatigue loading, the stiffness decrease in short-fiber reinforced polymers reflects the gradual degradation of the material. Thus, both measuring and modeling this stiffness is critical to investigate and understand the entire fatigue process.

To predict the nonlinear mechanical behavior of components made of short fiber-reinforced plastics (SFRP) under long term and cyclic loading, coupled process and component simulations are required. The injection molding process leads to locally varyi

Characterizing short-fiber reinforced polymers under high-cycle fatigue loading is a tedious experimental task. To reduce the necessary experiments to a minimum, we introduce a computational strategy involving a mean-stress dependent fatigue-damage m

Epoxy based molding compounds are typically used as an encapsulation material. Their role is to protect integrated circuitry from harsh environment. Typically, in standard IC packages we have materials with different coefficient of thermal expansion
