Tapered double cantilever beam specimens produced from two sheet molding compounds (SMC) with different glass contents were subjected to static loading in an environment of 1 M hydrochloric acid (HCl). The nature of the resulting crack growth was observed and the rate of crack growth was measured as a function of applied stress intensity, KI. Both direct visual observation of the crack length and indirect crack length estimations via compliance measurements were used to follow the failure of the specimen. It was discovered that slow crack growth occurs, producing an irregular and diffuse crack, until the total cracked area ahead of the original notch exceeds a distance equal to a characteristic length that is constant for each SMC. This cracked length may be determined in separate fracture mechanics testing of the materials in the absence of the environment. Once the critical crack length is achieved, the rate of crack growth increases. Both the time to achieve the critical cracked length and the subsequent rate of crack growth are functions of the applied stress intensity, KI.

ASTM International grants to the Subscriber and Authorized Users at the Subscriber's Authorized Site, online access to ASTM's journal for which the Subscriber maintains a current subscription to the print or online version. This grant extends only to the Subscriber and such Authorized Users individually and may not be transferred to, or extended to, others.

Verification: ASTM has the right to verify compliance with this License Agreement, at its expense, and at any time during the course of normal business hours. To do so, ASTM will engage an independent consultant, subject to a confidentiality agreement, to review your use of ASTM Documents. You agree to permit access to your information and computer systems for this purpose. Verification will take place upon no less than 15 days notice, during normal business hours and in a manner that does not interfere unreasonably with your operations.

Definitions. For purposes of this License, an Authorized Site is a localized site (one geographical location) that is under a single administration at a single location. For a Subscriber with locations in more than one city, each city is considered to be a different site. For a Subscriber with multiple locations in the same city, each location is considered to be a different site. (If you are seeking online access for multiple sites, please contact Kathe Hooper, ASTM International, at email@example.com or phone: 610-832-9634). Authorized User means only the employees, faculty, staff, and students officially affiliated with the Subscriber at the Authorized Site, and persons with legal access to the library's collections and facilities at the Authorized Site, using an IP address within the range identified in the subscription. Authorized Users may be persons remote from the Subscriber's physical location whose access is administered from the Authorized Site, but not persons at remote sites or campuses with separate administrations. For example, an employee of the Subscriber may be considered to be an Authorized User when accessing the Subscriber's network from home or while traveling to another city; however, employees of a branch campus or facility in another city are not considered to be Authorized Users. Subscriber is the person or entity which has subscribed to the ASTM journal and agreed to the terms of this limited license.
