Failure of Composites with Short Fibers

open access: yesCommunications, 2010
Strength-based failure criteria are commonly used with the finite element method (FEM) to predict failure events in composite structures. The laminate analogy is very useful for the calculation of the strength of composite materials with short fibers ...

Evaluation of the Bearing Capacity of the Board Pile in Collapsible Soil using A Laboratory Model [PDF]

open access: yesE3S Web of Conferences, 2023
The pile’s ultimate capacity or failure load must be computed by some criteria using load-settlement curve data gathered during the pile load test. Many scholars have proposed several approaches for evaluating the pile’s ultimate capacity in the past ...

Failure to Launch, Failure to Achieve Criteria for Adulthood? [PDF]

open access: yesJournal of Adolescent Research, 2010
In the West it is not until the mid-20s or 30s people reach an adult status. Becoming an adult signifies being independent from others (especially from parents) and learning to stand alone as a self-sufficient person. This study investigates whether the attainment of such individual qualities are affected by emerging adults’ living circumstances ...
